The design and construction issues of super-large-sections tunnels urgently need to be addressed. The Xiabei mountain No.1 and No.2 tunnels in the Hangzhou-Taizhou Railway are typical shallow-buried super-large-section-tunnels in weak surrounding rock, and their design and construction issues are representative. Eleven monitoring sections were set up in the tunnel, including tunnel deformation, surrounding rock, shotcrete, steel frames, bolts and temporary support mechanical responses. Taking the monitoring data of the most typical cross-section as an example, the mechanical response of the support structure of a shallow-buried super-large-section tunnel was analyzed in detail. Based on previous research results, this paper discusses and summarizes the common construction problems of this type of tunnel, and puts forward corresponding suggestions. The existing formula for calculating surrounding rock pressure has poor applicability to super-large-section tunnels constructed by step excavation, resulting in conservative support parameters. Therefore, based on the monitoring values of surrounding rock pressure at 10 monitoring sections in Xiabei mountain No. 1 and No.2 tunnels, empirical parameters reflecting the impact of step excavation were summarized. Based on the Wang formula and combined with the step excavation empirical parameters, an empirical formula for the surrounding rock pressure of shallow-buried super-large-section tunnels considering step excavation was constructed. The calculated results are in good agreement with the on-site monitoring data. This study can provide a good reference for similar projects.

Typical super-large-section traffic tunnels include: Gongbei tunnel, Longding tunnel and so on [ 31 , 45 ]. These types of tunnels are often constructed using a step excavation method, during which the surrounding rock and support structure are constantly disturbed by step excavation, and the construction mechanical response becomes more complex [ 16 , 19 , 44 ]. Exploring the above issues can effectively guide design and construction, which is of great significance for the construction of such tunnels. The study of the above issues through model test and numerical simulation methods has the characteristics of flexibility and simplicity, and many scholars have conducted in-depth discussions. Li used large-scale geo-mechanical model tests to study the failure characteristics and dynamic pressure arch phenomenon of large-section tunnels at different burial depths [ 7 , 8 ]. Wang studied the stress and deformation characteristics of composite arches and steel frames in large-section tunnels using model testing methods [ 31 ]. Zhang et al. conducted model test base on the Xinwu super-large-section tunnel, and the deformation of surrounding rock, cracking of lining, stress, and bearing capacity of lining in the experiment were analyzed and discussed [ 37 ]. Some researchers used numerical simulation methods to investigate the mechanical response and construction methods of super-large-section tunnel construction [ 3 , 4 , 9 , 11 , 15 , 16 , 18 , 21 , 25 , 33 , 34 , 44 ]. However, numerical simulation and model testing are difficult to fully reproduce the on-site situation, and the actual on-site monitoring results are still crucial. Numerous scholars have used on-site monitoring methods to investigate the mechanical response of super-large-section tunnel [ 38 , 39 , 40 , 41 , 46 , 47 ]. Li et al. discussed the failure mechanism of super-large-section tunnels in near horizontal strata based on monitoring data [ 10 ]. Zhang et al. analyzed the surface deformation of a super-large-section tunnel constructed by the freezing method based on on-site monitoring data [ 36 ]. Li et al. investigated the distribution and variation patterns of surrounding rock pressure in large-section tunnels based on on-site monitoring data [ 7 ]. Luo et al. monitored and analyzed the support mechanical response of the Badaling super-large-section underground station [ 17 ]. The applicability of existing standardized methods for calculating surrounding rock pressure in super-large-section tunnels is poor, and related research has also attracted the attention of many scholars. Lei et al. derived a formula for calculating surrounding rock pressure based on the Terzaghi theory combined with nonlinear yield criteria [ 5 ]. Luo et al. studied the geological response curve of super-large-section tunnels in strain softened rock masses using analytical methods [ 20 ]. Gao et al. discussed the formula for calculating the surrounding rock pressure of super-large-span tunnels [ 2 ]. Luo et al. derived a formula for calculating the surrounding rock pressure of large-span tunnels considering step excavation, enriching relevant research results [ 22 , 23 ]. Based on the research results, it is known that the support mechanical response and surrounding rock pressure of super-large-section tunnels are more complex than conventional tunnels. If constructed in weak and fractured strata with shallow overburden, the above problems will worsen. Therefore, this article conducts the following research work based on the Xiabei mountain tunnel under the Hangzhou-Taizhou high-railway, which is a shallow-buried super-large-section tunnel in weak surrounding rock. Firstly, based on on-site monitoring of tunnel deformation, surrounding rock pressure, shotcrete mechanical response, steel frame mechanical response, temporary support mechanical response, and bolts axial force, the deformation and mechanical characteristics are analyzed. Through discussion with similar engineering monitoring results, the mechanical response of the support structure of this type of tunnel is summarized. Secondly, based on the formula for calculating the safety factor of shotcrete in the TB 10003 − 2016. 2016 [ 28 ]. Code for design of railway tunnel, the safety and economic issues of the support structure design of the tunnel are determined. Finally, based on the surrounding rock pressure monitoring data of 10 sections in Xiabei mountain tunnel, empirical parameters considering step excavation were constructed. Base on the step excavation empirical parameters, the calculation formula for the surrounding rock pressure of shallow-buried super-large-section tunnels was derived. For super-large-section tunnels excavated by step excavation, compared to traditional formulas, this formula calculates accurately and can obtain the surrounding rock pressure values for each pilot tunnel. The research results of this article have good reference value for similar engineering. 2 Engineering background 2.1 Geological overview The Xiabei mountain Tunnel of the Hangzhou-Taizhou high speed railway is located in Taizhou, Zhejiang Province, China (Fig. 1 (a)). The Xiabei mountain tunnel No. 2 passes through the hilly terrain of eastern Zhejiang. The terrain of the tunnel site is undulating, with a slope of 25°~45°, and the mountain is covered by the Quaternary soil layer (Fig. 1 (b)). The depth range of the tunnel is only 6 ~ 35m, and the east side of the tunnel is adjacent to the cemetery and high-voltage power tower, which requires relatively high deformation control of the surrounding rock. The longitudinal section diagram of the tunnel is shown in Fig. 1 (c), the surface is covered with a layer of silty clay with a thickness of 0.5-4m. The excavation area of the tunnel is completely weathered and strongly weathered tuff. There are clay interlayers with a thickness of 10-50mm in joints. Based on the BQ system, it is determined that the entrance section is mainly composed of class V surrounding rock, while the tunnel section is mainly composed of class III and IV surrounding rock. At the same time, due to the need to reserve high-speed railway lines, the tunnel is designed as a four line type. When crossing the Xiabei mountain, the thickness range of the soil cover is only 6-35m. The east side of the tunnel is adjacent to the cemetery and high-voltage power tower, and the requirements for controlling the deformation of the surrounding rock are relatively high. 2.2 Design and construction overview The tunnel is constructed using the drilling and blasting method, with an excavation span and excavation area of 26.3m and 361.4m 2 , respectively. Based on TB 10003 − 2016. 2016. Code for design of railway tunnel. and Zhao et al. determined that the burial depth of the Xiabei mountain tunnel is shallow [ 28 , 42 ]. Due to the excavation span reaching 26.3m, in order to reduce the disturbance of excavation on the surrounding rock, choose the double-side-wall pilot tunnel method for construction. In the on-site study, a total of 10 cross-sections were monitored. Considering that shallow-buried super-large-section tunnels with class V rock mass are more rare and have research value, the DK215 + 105 section with the most unfavorable rock mass strength in the tunnel was selected as the key research object to study the deformation and mechanical characteristics of the primary support system during the construction period. Due to the lack of similar engineering experience during construction, the common types of tunnels are Class III and Class IV deep-buried super-large-section tunnels with surrounding rocks, and the current tunnel design specifications do not provide support design guidance for four line tunnels [ 1 , 6 , 27 , 32 ]. Therefore, when designing the support of this tunnel, only a small number of engineering cases can be relied on for analogy design, and the design parameters are relatively conservative. The specific primary support parameters for class V surrounding rock are shown in Fig. 2 (a). The specific construction process includes 8 steps, and the excavation sequence of the double-side-wall pilot tunnel method is shown in Fig. 2 (b): (1) Excavation of left and right pilot tunnels: 1) Excavate the upper steps of the left pilot tunnel, and the excavation cycle footage is a steel frame (1.2m). Apply the primary shotcrete (including peripheral shotcrete and temporary shotcrete) around this part. Construction Φ 32 self-drilling bolts with a length of 6m, a circumferential spacing of 0.8m, and a longitudinal spacing of 0.8m. Erect the steel frame at the arch section, and set up feet-lock bolt at an inclination angle of 30°, close to the edges of both sides of the steel frame at a height of about 30cm above the arch foot. The feet-lock bolt are firmly welded to the steel frame, and the excavation is 2.4m. 2) The construction method for the lower step of the left pilot tunnel is the same as that for the upper step. 3) The construction method for the right and left pilot tunnels is the same, with a construction spacing of 2.4m between each part. (2) To reduce the impact of excavation blasting vibration, one to four inner side walls and horizontal temporary steel frames will be erected approximately 10 meters away from the front face of the tunnel. (3) Excavation of part 5 of the main tunnel: Excavation is divided into two parts: left and right. After excavation, primary support and temporary support are provided, with a distance of 2.4m between the left and right parts. Finally, the primary supports will be closed. (4) Demolition of temporary supports: After excavation of part 5, in order to minimize the transmission of disturbing from part 6 and 7 to the primary support of the closed primary support, the temporary steel frames in parts 1–5 are removed. (5) Excavate parts 6 and 7 and application of shotcrete to the design thickness. (6) After the primary support closure, steel fiber reinforced concrete was sprayed for reinforcement, lagging behind the primary support closure by 2.4m. (7) Spray a 1cm thick cement mortar protective layer. (8) Construction the secondary lining concrete. The physical and mechanical parameters of the monitoring section surrounding rock are shown in Table 1 . Table 1 Physical and mechanical parameters of the rock mass in the monitoring section. Stratum Elastic modulus (GPa) Poisson's ratio Cohesion (kPa) Internal friction angle (°) Density (kN·m − 3 ) Residual soil 0.07 0.42 31 25.5 19.5 Tuff 0.52 0.26 113 27.3 25.7 3 Analysis of surrounding rock and support structures on-site monitoring 3.1 Monitoring scheme As shown in Fig. 3 ., the monitoring schemes include deformation monitoring and mechanical monitoring. The deformation monitoring location is located at section DK215 + 110, where the tunnel is buried at a depth of 31m, as shown in Fig. 3 (a), deformation monitoring includes one vertical settlement monitoring point and two horizontal convergence monitoring points for the left and right pilot tunnels. The tunnel mechanical monitoring point is located at DK215 + 105, 5m away from the deformation monitoring position, as shown in Fig. 3 (b) shows the tunnel mechanical monitoring schemes, including: earth pressure cell, reinforcement stress meter, concrete strain gauge, and bolt axial force meter. 3.2 Analysis of deformation This article stipulates that deformation monitoring results should be positive for deformation inside the tunnel and negative for deformation outside the tunnel. As shown in Fig. 4 ., the deformation trend of the tunnel first increases rapidly and then tends to stabilize, which is consistent with previous monitoring results. The monitoring of tunnel deformation starts after the excavation of the upper steps of the main tunnel, so the horizontal convergence values of the left and right guide tunnels are more stable and smaller compared to the vertical settlement. The horizontal convergence of the left pilot tunnel is smaller than that of the right pilot tunnel, because the left pilot tunnel is excavated before the right pilot tunnel, resulting in a longer deformation stability time. Due to the small difference in horizontal convergence values, it can be considered that the deformation of the left and right pilot tunnels is symmetrical. The negative horizontal convergence value indicates that the surrounding rocks on both sides are expanding outward from the tunnel. The reason is that the high span ratio of super-large-span tunnels is small, and the loading of arch crown is transmitted to the tunnel walls through steel frame, ultimately leading to outward expansion on both sides of the tunnel. This also indicates that the steel frame and feet-lock bolt combined support structure used in super-large-span tunnels has a good effect on sharing the load on the arch crown and reducing the vertical settlement. Compared with horizontal convergence, the vertical settlement is larger. On the one hand, this is because the monitoring time of vertical settlement is more complete; on the other hand, it indicates that the load borne by the arch is higher than that on both sides of the tunnel. The reason for the significant fluctuations of the vertical settlement is due to the disturbance by step excavation. The three-step excavation of the main tunnel resulted in a higher number of disturbances, but overall, the vertical settlement was within an acceptable range. During the stable deformation period, there is a small fluctuation in deformation due to the temporary support removal. 3.3 Analysis of mechanical 3.3.1 Surrounding rock pressure The mechanical monitoring results in this article are positive for tension and negative for pressure. As shown in Fig. 5 . (a), the maximum value of surrounding rock pressure is 157.8kPa, located at the right spandrel. From the distribution perspective, the phenomenon of excessive surrounding rock pressure in the first pilot tunnel of Xiabei mountain No.2 tunnel is relatively mild compared to the monitoring results of Zhao et al. [ 42 ]. The main reason is that the temporary support parameters for the Xiabei mountain No. 2 tunnel are more conservative, reducing the transfer of loads from the later pilot tunnel rock mass to the first pilot tunnel, as well as the disturbance caused by step excavation. The temporary support of the Qichong village tunnel is made of 15cm thick C25 shotcrete, with the same steel frame and steel mesh model as the Xiabei mountain No.2 tunnel. The overall strength of the support structure is lower than that of the Xiabei mountain No.2 tunnel. Moreover, during the temporary support of the Xiabei mountain No.2 tunnel, bolts will be applied in the direction of the main tunnel, greatly enhancing the mechanical performance of the temporary support. Compared with the Qichong village tunnel, in addition to the higher strength of the temporary support structure, the burial depth of the Xiabei mountain No. 2 tunnel is deeper. From this, it can be seen that calculating the overburden weight alone is not enough to determine the surrounding rock pressure of this type of tunnel. The calculation method for the surrounding rock pressure of super-large-section tunnels using the step excavation method still needs further discussion. As shown in Fig. 5 . (b), the development trend of surrounding rock pressure shows a rapid increase and then a gradually stable trend, which is similar to the monitoring results of Luo et al., Zhou et al., Zhao et al. and others [ 19 , 42 , 45 ]. The fluctuation section in the middle of the time history curve is mainly caused by step excavation. Among them, the excavation of the upper steps of the main tunnel has a significant impact on the surrounding rock pressure of the vault, and after the excavation of the upper steps of the main tunnel, the surrounding rock pressure of the vault has increased by more than twice. It can be seen that even if the temporary support strength is high, the surrounding rock pressure of the super-large-section tunnel excavated in stages is still affected by the step excavation, and it will have a significant impact. 3.3.2 Shotcrete axial force The axial force distribution of the primary support shotcrete is shown in Fig. 6 (a). The shotcrete is in a compressed state as a whole, with the maximum axial force located at the left spandrel; The minimum axial force is located on the left of inverted arch. The overall axial force of the lower step is smaller than that of the upper step. Based on the deformation monitoring results, it can be concluded that the combined support system composed of steel frame and feet-lock bolt has a good effect on limiting deformation and bearing capacity of the upper step. Figure 6 (b) shows the time history curve of the axial force of the primary support shotcrete. The excavation of main tunnel has a significant impact on the shotcrete axial force. The excavation of main tunnel increases the axial force of the left and right arch waists by about − 3540kN and − 3160kN, respectively. After the excavation of the middle and lower steps of the main tunnel, except for the lower axial force on the right side reaching 1068kN, which exceeded the tensile strength of the concrete, the measured values at all other measuring points showed a sudden upward trend. It can be seen that step excavation has a significant impact on the axial force of other pilot tunnels. 3.3.3 Steel frame axial force and bending moment The mechanical distribution of the steel frame is shown in Fig. 7 (a) and (b). The mechanical distribution of steel frame also has the characteristics that the upper structure is greater than the lower structure. The maximum axial force is located on the left and right arch waists, and the maximum bending moment is also located on the left and right arche waists. It can be seen that the arch waist undergoes significant deformation towards the tunnel outside because of the vault load, and the support here should be strengthened. From Fig. 8 (a), It can be seen that after the excavation of the upper steps of the left and right pilot tunnels, the axial force on the steel frame rapidly increases to -35~-30kN, and then tends to stabilize until before the excavation of the upper steps of the main tunnel. After the excavation of the upper steps on the main tunnel, the axial force on the left and right arch waists increased by about − 100~-60kN, which was more than twice as much as before. It can be seen that the excavation of the upper step on the main tunnel has a significant impact on the support structures of the left and right pilot tunnels. After the main tunnel is excavated, the stress on both sides of the arch waist significantly increases, indicating that it is necessary to enhance temporary support to assist in bearing the vault load before excavating the main tunnel. 3.3.4 Bolts axial force To analyze the effect of bolts, draw the axial force distribution of bolts on the monitoring section as shown in Fig. 9 .. It can be seen that after the tunnel excavation is completed, the bolts at the vault do not have a significant tensile effect, this is similar to previous research results [ 42 ]. The bolts on both sides of the tunnel have a good effect on suppressing the deformation of the surrounding rock and should not be cancelled. For super-large-section tunnels, the role of the feet-lock bolt is not only to anchor the rock, but more importantly, to combine with the steel frame, thereby limiting the displacement of the steel frame, and avoid significant vertical settlement. As shown in Fig. 9 ., the feet-lock bolt is under compression, indicating that the feet-lock bolt has not played a role in anchoring the rock mass, which is inconsistent with existing monitoring results. In order to combing with steel frame, the feet-lock bolt needs to be welded to the steel frame. When the surrounding rock is relatively loose, the load on the vault is transmitted to both sides, causing the feet-lock bolt and steel frame to compress the surrounding rock on both sides together, generating pressure. Although the feet-lock bolt did not have the effect of anchoring the rock mass, combined with deformation, surrounding rock pressure, and steel frame axial force monitoring results, it can be seen that feet-lock bolt plays a significant role in limiting the vertical settlement and sharing the surrounding rock pressure. Overall, the bolts on the vault has almost no effect on reinforcing the rock mass and supporting the bearing capacity of the supporting structure, which is similar to the research results of Zhao et al. [ 42 ]. It can be seen that the bolts on the vault for shallow-buried super-large-section tunnels can be cancelled and replaced by stronger shotcrete, steel frames, or temporary supporting structures. 3.3.5 Temporary support structures axial force and bending moment The axial force and bending moment monitoring curve of the temporary support steel frame is shown in Fig. 10 .. The excavation of the lower steps of the left pilot tunnel and the upper steps of the main tunnel has a significant impact on the axial force of the steel frame. After the excavation of the middle and lower steps of the main tunnel, the monitoring points for axial force 1, 2, and 3, as well as bending moment 2, and 3, almost decreased to 0. The temporary support has a significant limiting effect on the soil of the main tunnel, indicating the necessity of temporary support. The step excavation has caused frequent adjustment of the force on the temporary support steel frame. After the excavation of the middle and lower steps of the main tunnel, the support force provided by the steel frame has significantly decreased. This indicates that the temporary support structure has a very significant limiting effect on the pressure of the vault surrounding rock. Combined with Fig. 5 .~Fig. 8 ., it can be seen that from the removal of temporary support to the construction of secondary lining, the primary support stress increases again, indicating that the removal of temporary support will lead to stress redistribution again. Therefore, when dismantling temporary support structures, emphasis should be placed on monitoring displacement and stress changes. 3.4 Analysis of safety factor of support structure The safety factor calculation of shotcrete in the TB 10003 − 2016. 2016. Code for design of railway tunnel. can effectively quantify the safety of support structures [ 28 ]. According to the monitoring results, the minimum safety factor of shotcrete at each step of the monitoring section during the construction process and the axial force and bending moment at its position are calculated, as shown in Table 2 and Table 3 . When calculating, the compressive strength of concrete is taken as 20.1MPa, and the tensile strength is taken as 2.01MPa. Table 2 Minimum safety factor for primary support shotcrete. Table 3 Minimum safety factor for temporary support shotcrete. According to Table 2 and Table 3 , the minimum safety factor and its location of the shotcrete on the monitoring section are constantly changing with the construction process. The position with the lowest safety factor mostly occurs in the left pilot tunnel, especially the upper steps, which once again confirms the phenomenon that the first pilot tunnel is affected by the excavation of the subsequent pilot tunnels. Excavation also has a significant impact on adjacent support structures. For primary support, excavation of the main tunnel and construction of the inverted arch have the greatest disturbance; for temporary support, the excavation of the main tunnel causes the greatest disturbance. Overall, the primary support of Xiabei mountain No.2 tunnel fully meets the safety requirements, and the safety factor of the left pilot tunnel has been significantly reduced due to multiple disturbances. Therefore, for this type of tunnel, the primary and temporary support of the first pilot tunnel can be enhanced, while the primary and temporary support of other parts can be appropriately reduced. The existing calculation formula for surrounding rock pressure cannot reflect the above issues, and its effectiveness in guiding the design and construction of such tunnels is limited. 4 Calculation formula for surrounding rock pressure considering step excavation 4.1 Overview Based on Section 3 analysis of the support mechanical response of the Xiabei mountain No.2 tunnel, it was found that the surrounding rock pressure of the super-large-section tunnel is influenced by many factors, including: (1) The limitation of temporary support structures on surrounding rock pressure; (2) The influence of spatial effects on each pilot tunnel during segmented excavation; (3) Deterioration effect of surrounding rock in post excavation pilot tunnel. Obviously, it is difficult to consider all the above factors through theoretical formulas, but in fact, the reason for the change in surrounding rock pressure can be attributed to step excavation. According to the analysis results in Section 3, it can be concluded that the first pilot tunnel is affected by the disturbance of the later pilot tunnel, and the surrounding rock pressure will continue to rise. Luo et al. constructed a surrounding rock pressure calculation method considering the mutual influence of left and right pilot tunnels based on surrounding rock pressure monitoring data, and achieved good application results [ 22 , 23 ]. The reasonable construction of an empirical model for surrounding rock pressure based on monitoring data has a good application effect on super-large-section tunnels with complex construction mechanical responses. In addition to section DK215 + 105, this article also monitored the surrounding rock pressure of the other four sections of Xiabei mountain No.2 tunnel and five sections of Xiabei mountain No.1 tunnel. Xiabei mountain No.1 tunnel is only more than 200 meters away from Xiabei mountain No.2 tunnel, and the tunnel lithology is similar to that of tunnel sections, all of which are shallow buried tunnels. Based on sufficient monitoring data, an empirical formula for surrounding rock pressure considering step excavation is constructed. 4.2 Calculation formula for surrounding rock pressure Based on the calculation formula for surrounding rock pressure proposed by Wang et al., a formula for calculating surrounding rock pressure considering the influence of distributed excavation is constructed (Eq. ( 1 )) [ 30 ]. Firstly, simplify the tunnel excavated by the double-side-wall pilot tunnel method into three straight wall arched tunnels. Then, through Eq. ( 1 ) calculate the surrounding rock pressure of three pilot tunnels without the influence of step excavation. Calculate the empirical parameters of step excavation based on measured surrounding rock pressure data. The final rock pressure value can be obtained by combining the surrounding rock pressure without the influence of step excavation with the step excavation empirical parameters. At this point, the surrounding rock pressure of the first pilot tunnel is Eq. ( 6 ), the surrounding rock pressure of the second excavation of the pilot tunnel is Eq. ( 7 ), the final pilot tunnel was not disturbed subsequently, so it was directly obtained. The final surrounding rock pressure of the tunnel is the highest surrounding rock pressure among the three pilot tunnels (Eq. ( 8 )). The specific calculation model is shown in Fig. 11 .. $$p=\frac{{\frac{{\gamma \tan \alpha `}}{2}}}{{1 - \frac{{m\tan \alpha `}}{2}}} \cdot D$$ 1 $$m= - \frac{2}{{\tan \alpha `}}+\frac{{4({{\sin }^2}\theta _{{1H}}^{s}+{K_a}{{\cos }^2}\theta _{{1H}}^{s}){{\cos }^2}\varphi \cos \alpha `}}{{[1+{K_a} - \frac{{(1 - {K_a})\sin \theta _{{1H}}^{s}\cos \theta _{{1H}}^{s}}}{{\theta _{{1H}}^{s}}}] \cdot [1 - \sin (2\alpha `+\varphi )\sin \varphi ]}}$$ 2 $$\theta _{{1H}}^{s}=\frac{{\arctan (\frac{{4\lambda }}{{1+4{\lambda ^2}}})}}{{\pi /4}}\varphi +\frac{\pi }{4} - \frac{\varphi }{2}$$ 3 $$\alpha `=\frac{{\arctan (\frac{{4\lambda }}{{1+4{\lambda ^2}}})}}{{\pi /4}}\varphi +\frac{\pi }{2} - \varphi$$ 4 $$\lambda =\frac{{\Delta u}}{D}$$ 5 Where, γ is the density of soil, α ` is angle between the shear plane and the horizontal direction, m is a parameter related to φ (soil strength), θ s 1H (principal stress rotation angle) and α `( shear plane rotation angle). $${q_1}`={k_1}{q_2}+{k_2}{q_3}+{q_1}$$ 6 $${q_2}`={k_3}{q_3}+{q_2}$$ 7 Where, k 1 , k 2 , k 3 are the step excavation empirical parameters, determined by the measured changes in surrounding rock pressure from multiple monitoring sections; q 1 , q 2 , q 3 are the initial rock pressures of the first pilot tunnel, the second pilot tunnel, and the main tunnel, respectively, determined by Eq. ( 1 ); q 1 ` and q 2 ` respectively represent the surrounding rock pressure of the first and second pilot tunnels affected by step excavation. $${q_{ultra}}=\hbox{max} \left( {{q_1}`,{q_2}`,{q_3}} \right)$$ 8 Where, q ultra is the final surrounding rock pressure value. 4.3 The step excavation empirical parameters The distribution of surrounding rock pressure in other monitoring sections is shown in Fig. 12 .. The main steps for calculating the step excavation empirical parameters are as follows: 1. Statistics the maximum surrounding rock pressure values at different pilot tunnel of each monitoring section; 2.

The result of monitoring section 3 shows a significant deviation compared to other sections, due to the presence of a slip layer above the left pilot tunnel, which has a significant impact on the universality of the results. According to the Shoveler principle, it should be excluded. In summary, based on the average value of the monitoring data mentioned above, the step excavation empirical parameters can be obtained as k 1 = 0.0845, k 2 = 0.4777, k 3 = 0.1613. 4.4 Verification The specific verification steps for section DK215 + 105 are as follows: 1. As shown in Fig. 12 ., the section DK215 + 105 of Xiabei mountain No.2 tunnel is simplified into a mechanical model consisting of three straight wall arched tunnels. 2. Using Eq. ( 1 ) calculate the surrounding rock pressure of three straight wall arch tunnels to obtain q 1 , q 2 and q 3 . 3. Substitute q 1 , q 2 and q 3 into Eq. ( 6 ) ~ Eq. ( 7 ) obtain q 1 ` and q 2 `. 4. Using Eq. ( 8 ) obtain the maximum surrounding rock value of the monitoring section. As shown in Table 5 , the calculation results indicate that the proposed theoretical calculation model for surrounding rock pressure is more accurate, and can also calculate the surrounding rock pressure of each of the three pilot tunnels in step excavation, providing a good reference for tunnel engineering using segmented excavation. Table 5 Calculation results and comparison of surrounding rock pressure. Calculation methods Calculation results (kPa) Parameter description First Second Main RMR method 494.5 S RMR =26, B = 26m, γ = 25.7kN·m -3 Terzaghi method 580.1 ~ 796.7 The height of the soil cover is 31m, and the height of the stratum arch H pt = 22.6 ~ 31m Proposed method 133.0 82.5 143.8 - Monitoring values 87.3 61.5 157.8 - 5 Conclusion Based on the measured monitoring data of Xiabei mountain No. 1 and No. 2 tunnel, the mechanical response of the support structure of a super-large-section tunnel with weak surrounding rock was analyzed, and a calculation formula for the surrounding rock pressure of a shallow-buried super-large-section tunnel suitable for the use of step excavation method was derived. The main conclusions obtained from the study are as follows: When using the double-side-wall pilot tunnel method to excavate shallow-buried super-large-section tunnels in weak strata. The deformation and stress of the primary support of the tunnel not only go through a rapid development stage and a stable stage, but also fluctuate during step excavation and removal of temporary support. The application of feet-locking bolts and welding with steel frame effectively shares the pressure on the surrounding rock of the vault and limits the vertical settlement. Therefore, when excavating shallow-buried super-large-section tunnels in weak strata, special attention should be paid to the deformation and stress situation during step excavation construction nodes and temporary support dismantling, and the feet-locking bolts should be actively applied to optimize the primary support stress. Applying high-strength temporary support and applying bolts to soil of unexcavated pilot tunnels can effectively reduce the impact of subsequent pilot tunnel excavation on the first excavated pilot tunnel. Temporary support can effectively assist steel frame in bearing the surrounding rock pressure of the vault. The excavation of the upper steps of main tunnel will significantly affect the surrounding rock pressure of other pilot tunnels. Due to the influence of step excavation, the trend of surrounding rock pressure changes is complex, and existing formulas for calculating surrounding rock pressure or directly calculating the weight of the overlying soil layer are difficult to meet the design and construction requirements of such tunnels. The position with the lowest safety factor mostly occurs in the left pilot tunnel, especially on the upper steps of left pilot tunnel. For primary support, excavation of the main tunnel and construction of the inverted arch have the greatest disturbance; for temporary support, the excavation of the main tunnel causes the greatest disturbance. It can be seen that the safety factor of excavating the first pilot tunnel is slightly insufficient due to multiple disturbances. For shallow-buried super-large-section tunnels in weak surrounding rock that adopt step excavation, the primary and temporary support of the first pilot tunnel can be enhanced, while the primary and temporary support of other parts can be appropriately reduced. Based on the measured rock pressure data of 10 monitoring sections of the Xiabei mountain No. 1 and No. 2 tunnel, an empirical parameter was proposed using data analysis to determine the impact of step excavation. Based on this, a calculation formula for surrounding rock pressure considering step excavation has been constructed. Compared with existing methods, this formula can more accurately calculate the surrounding rock pressure of super-large-section tunnels, and can also calculate the surrounding rock pressure of each pilot tunnel. It has certain application value for shallow-buried super-large-section tunnels in weak surrounding rock using step excavation.

The depth range of the tunnel is only 6\u0026thinsp;~\u0026thinsp;35m, and the east side of the tunnel is adjacent to the cemetery and high-voltage power tower, which requires relatively high deformation control of the surrounding rock.

Based on the BQ system, it is determined that the entrance section is mainly composed of class V surrounding rock, while the tunnel section is mainly composed of class III and IV surrounding rock. At the same time, due to the need to reserve high-speed railway lines, the tunnel is designed as a four line type. When crossing the Xiabei mountain, the thickness range of the soil cover is only 6-35m. The east side of the tunnel is adjacent to the cemetery and high-voltage power tower, and the requirements for controlling the deformation of the surrounding rock are relatively high.\u003c/p\u003e\n\u003c/div\u003e\n\u003cdiv id=\"Sec4\" class=\"Section2\"\u003e\n \u003ch2\u003e2.2 Design and construction overview\u003c/h2\u003e\n \u003cp\u003eThe tunnel is constructed using the drilling and blasting method, with an excavation span and excavation area of 26.3m and 361.4m\u003csup\u003e2\u003c/sup\u003e, respectively.

As shown in Fig. \u003cspan class=\"InternalRef\"\u003e4\u003c/span\u003e., the deformation trend of the tunnel first increases rapidly and then tends to stabilize, which is consistent with previous monitoring results. The monitoring of tunnel deformation starts after the excavation of the upper steps of the main tunnel, so the horizontal convergence values of the left and right guide tunnels are more stable and smaller compared to the vertical settlement. The horizontal convergence of the left pilot tunnel is smaller than that of the right pilot tunnel, because the left pilot tunnel is excavated before the right pilot tunnel, resulting in a longer deformation stability time. Due to the small difference in horizontal convergence values, it can be considered that the deformation of the left and right pilot tunnels is symmetrical. The negative horizontal convergence value indicates that the surrounding rocks on both sides are expanding outward from the tunnel. The reason is that the high span ratio of super-large-span tunnels is small, and the loading of arch crown is transmitted to the tunnel walls through steel frame, ultimately leading to outward expansion on both sides of the tunnel. This also indicates that the steel frame and feet-lock bolt combined support structure used in super-large-span tunnels has a good effect on sharing the load on the arch crown and reducing the vertical settlement. Compared with horizontal convergence, the vertical settlement is larger. On the one hand, this is because the monitoring time of vertical settlement is more complete; on the other hand, it indicates that the load borne by the arch is higher than that on both sides of the tunnel. The reason for the significant fluctuations of the vertical settlement is due to the disturbance by step excavation. The three-step excavation of the main tunnel resulted in a higher number of disturbances, but overall, the vertical settlement was within an acceptable range. During the stable deformation period, there is a small fluctuation in deformation due to the temporary support removal.\u003c/p\u003e\n\u003c/div\u003e\n\u003cdiv id=\"Sec8\" class=\"Section2\"\u003e\n \u003ch2\u003e3.3 Analysis of mechanical\u003c/h2\u003e\n \u003cp\u003e\u003cstrong\u003e3.3.1 Surrounding rock pressure\u003c/strong\u003e\u003c/p\u003e\n \u003cp\u003eThe mechanical monitoring results in this article are positive for tension and negative for pressure. As shown in Fig. \u003cspan class=\"InternalRef\"\u003e5\u003c/span\u003e. (a), the maximum value of surrounding rock pressure is 157.8kPa, located at the right spandrel. From the distribution perspective, the phenomenon of excessive surrounding rock pressure in the first pilot tunnel of Xiabei mountain No.2 tunnel is relatively mild compared to the monitoring results of Zhao et al. [\u003cspan class=\"CitationRef\"\u003e42\u003c/span\u003e]. The main reason is that the temporary support parameters for the Xiabei mountain No. 2 tunnel are more conservative, reducing the transfer of loads from the later pilot tunnel rock mass to the first pilot tunnel, as well as the disturbance caused by step excavation. The temporary support of the Qichong village tunnel is made of 15cm thick C25 shotcrete, with the same steel frame and steel mesh model as the Xiabei mountain No.2 tunnel. The overall strength of the support structure is lower than that of the Xiabei mountain No.2 tunnel. Moreover, during the temporary support of the Xiabei mountain No.2 tunnel, bolts will be applied in the direction of the main tunnel, greatly enhancing the mechanical performance of the temporary support. Compared with the Qichong village tunnel, in addition to the higher strength of the temporary support structure, the burial depth of the Xiabei mountain No. 2 tunnel is deeper. From this, it can be seen that calculating the overburden weight alone is not enough to determine the surrounding rock pressure of this type of tunnel. The calculation method for the surrounding rock pressure of super-large-section tunnels using the step excavation method still needs further discussion.\u003c/p\u003e\n \u003cp\u003eAs shown in Fig. \u003cspan class=\"InternalRef\"\u003e5\u003c/span\u003e. (b), the development trend of surrounding rock pressure shows a rapid increase and then a gradually stable trend, which is similar to the monitoring results of Luo et al., Zhou et al., Zhao et al. and others [\u003cspan class=\"CitationRef\"\u003e19\u003c/span\u003e, \u003cspan class=\"CitationRef\"\u003e42\u003c/span\u003e, \u003cspan class=\"CitationRef\"\u003e45\u003c/span\u003e]. The fluctuation section in the middle of the time history curve is mainly caused by step excavation. Among them, the excavation of the upper steps of the main tunnel has a significant impact on the surrounding rock pressure of the vault, and after the excavation of the upper steps of the main tunnel, the surrounding rock pressure of the vault has increased by more than twice. It can be seen that even if the temporary support strength is high, the surrounding rock pressure of the super-large-section tunnel excavated in stages is still affected by the step excavation, and it will have a significant impact.\u003c/p\u003e\n \u003cp\u003e\u003cstrong\u003e3.3.2 Shotcrete axial force\u003c/strong\u003e\u003c/p\u003e\n \u003cp\u003eThe axial force distribution of the primary support shotcrete is shown in Fig. \u003cspan class=\"InternalRef\"\u003e6\u003c/span\u003e (a). The shotcrete is in a compressed state as a whole, with the maximum axial force located at the left spandrel; The minimum axial force is located on the left of inverted arch. The overall axial force of the lower step is smaller than that of the upper step. Based on the deformation monitoring results, it can be concluded that the combined support system composed of steel frame and feet-lock bolt has a good effect on limiting deformation and bearing capacity of the upper step.\u003c/p\u003e\n \u003cp\u003eFigure \u003cspan class=\"InternalRef\"\u003e6\u003c/span\u003e (b) shows the time history curve of the axial force of the primary support shotcrete. The excavation of main tunnel has a significant impact on the shotcrete axial force. The excavation of main tunnel increases the axial force of the left and right arch waists by about \u0026minus;\u0026thinsp;3540kN and \u0026minus;\u0026thinsp;3160kN, respectively. After the excavation of the middle and lower steps of the main tunnel, except for the lower axial force on the right side reaching 1068kN, which exceeded the tensile strength of the concrete, the measured values at all other measuring points showed a sudden upward trend. It can be seen that step excavation has a significant impact on the axial force of other pilot tunnels.\u003c/p\u003e\n \u003cp\u003e\u003cstrong\u003e3.3.3 Steel frame axial force and bending moment\u003c/strong\u003e\u003c/p\u003e\n \u003cp\u003eThe mechanical distribution of the steel frame is shown in Fig. \u003cspan class=\"InternalRef\"\u003e7\u003c/span\u003e (a) and (b). The mechanical distribution of steel frame also has the characteristics that the upper structure is greater than the lower structure. The maximum axial force is located on the left and right arch waists, and the maximum bending moment is also located on the left and right arche waists. It can be seen that the arch waist undergoes significant deformation towards the tunnel outside because of the vault load, and the support here should be strengthened.\u003c/p\u003e\n \u003cp\u003eFrom Fig. \u003cspan class=\"InternalRef\"\u003e8\u003c/span\u003e (a), It can be seen that after the excavation of the upper steps of the left and right pilot tunnels, the axial force on the steel frame rapidly increases to -35~-30kN, and then tends to stabilize until before the excavation of the upper steps of the main tunnel. After the excavation of the upper steps on the main tunnel, the axial force on the left and right arch waists increased by about \u0026minus;\u0026thinsp;100~-60kN, which was more than twice as much as before. It can be seen that the excavation of the upper step on the main tunnel has a significant impact on the support structures of the left and right pilot tunnels. After the main tunnel is excavated, the stress on both sides of the arch waist significantly increases, indicating that it is necessary to enhance temporary support to assist in bearing the vault load before excavating the main tunnel.\u003c/p\u003e\n \u003cp\u003e\u003cstrong\u003e3.3.4 Bolts axial force\u003c/strong\u003e\u003c/p\u003e\n \u003cp\u003eTo analyze the effect of bolts, draw the axial force distribution of bolts on the monitoring section as shown in Fig. \u003cspan class=\"InternalRef\"\u003e9\u003c/span\u003e.. It can be seen that after the tunnel excavation is completed, the bolts at the vault do not have a significant tensile effect, this is similar to previous research results [\u003cspan class=\"CitationRef\"\u003e42\u003c/span\u003e]. The bolts on both sides of the tunnel have a good effect on suppressing the deformation of the surrounding rock and should not be cancelled. For super-large-section tunnels, the role of the feet-lock bolt is not only to anchor the rock, but more importantly, to combine with the steel frame, thereby limiting the displacement of the steel frame, and avoid significant vertical settlement. As shown in Fig. \u003cspan class=\"InternalRef\"\u003e9\u003c/span\u003e., the feet-lock bolt is under compression, indicating that the feet-lock bolt has not played a role in anchoring the rock mass, which is inconsistent with existing monitoring results. In order to combing with steel frame, the feet-lock bolt needs to be welded to the steel frame. When the surrounding rock is relatively loose, the load on the vault is transmitted to both sides, causing the feet-lock bolt and steel frame to compress the surrounding rock on both sides together, generating pressure. Although the feet-lock bolt did not have the effect of anchoring the rock mass, combined with deformation, surrounding rock pressure, and steel frame axial force monitoring results, it can be seen that feet-lock bolt plays a significant role in limiting the vertical settlement and sharing the surrounding rock pressure. Overall, the bolts on the vault has almost no effect on reinforcing the rock mass and supporting the bearing capacity of the supporting structure, which is similar to the research results of Zhao et al. [\u003cspan class=\"CitationRef\"\u003e42\u003c/span\u003e]. It can be seen that the bolts on the vault for shallow-buried super-large-section tunnels can be cancelled and replaced by stronger shotcrete, steel frames, or temporary supporting structures.\u003c/p\u003e\n \u003cp\u003e\u003cstrong\u003e3.3.5 Temporary support structures axial force and bending moment\u003c/strong\u003e\u003c/p\u003e\n \u003cp\u003eThe axial force and bending moment monitoring curve of the temporary support steel frame is shown in Fig. \u003cspan class=\"InternalRef\"\u003e10\u003c/span\u003e.. The excavation of the lower steps of the left pilot tunnel and the upper steps of the main tunnel has a significant impact on the axial force of the steel frame. After the excavation of the middle and lower steps of the main tunnel, the monitoring points for axial force 1, 2, and 3, as well as bending moment 2, and 3, almost decreased to 0. The temporary support has a significant limiting effect on the soil of the main tunnel, indicating the necessity of temporary support. The step excavation has caused frequent adjustment of the force on the temporary support steel frame. After the excavation of the middle and lower steps of the main tunnel, the support force provided by the steel frame has significantly decreased. This indicates that the temporary support structure has a very significant limiting effect on the pressure of the vault surrounding rock. Combined with Fig. \u003cspan class=\"InternalRef\"\u003e5\u003c/span\u003e.~Fig. \u003cspan class=\"InternalRef\"\u003e8\u003c/span\u003e., it can be seen that from the removal of temporary support to the construction of secondary lining, the primary support stress increases again, indicating that the removal of temporary support will lead to stress redistribution again. Therefore, when dismantling temporary support structures, emphasis should be placed on monitoring displacement and stress changes.\u003c/p\u003e\n\u003c/div\u003e\n\u003cdiv id=\"Sec9\" class=\"Section2\"\u003e\n \u003ch2\u003e3.4 Analysis of safety factor of support structure\u003c/h2\u003e\n \u003cp\u003eThe safety factor calculation of shotcrete in the TB 10003\u0026thinsp;\u0026minus;\u0026thinsp;2016. 2016.

of the shotcrete on the monitoring section are constantly changing with the construction process. The position with the lowest safety factor mostly occurs in the left pilot tunnel, especially the upper steps, which once again confirms the phenomenon that the first pilot tunnel is affected by the excavation of the subsequent pilot tunnels. Excavation also has a significant impact on adjacent support structures. For primary support, excavation of the main tunnel and construction of the inverted arch have the greatest disturbance; for temporary support, the excavation of the main tunnel causes the greatest disturbance.\u003c/p\u003e\n \u003cp\u003eOverall, the primary support of Xiabei mountain No.2 tunnel fully meets the safety requirements, and the safety factor of the left pilot tunnel has been significantly reduced due to multiple disturbances. Therefore, for this type of tunnel, the primary and temporary support of the first pilot tunnel can be enhanced, while the primary and temporary support of other parts can be appropriately reduced. The existing calculation formula for surrounding rock pressure cannot reflect the above issues, and its effectiveness in guiding the design and construction of such tunnels is limited.\u003c/p\u003e\n\u003c/div\u003e"},{"header":"4 Calculation formula for surrounding rock pressure considering step excavation","content":"\u003cdiv id=\"Sec11\" class=\"Section2\"\u003e\n \u003ch2\u003e4.1 Overview\u003c/h2\u003e\n \u003cp\u003eBased on Section 3 analysis of the support mechanical response of the Xiabei mountain No.2 tunnel, it was found that the surrounding rock pressure of the super-large-section tunnel is influenced by many factors, including:\u003c/p\u003e\n \u003cp\u003e(1) The limitation of temporary support structures on surrounding rock pressure;\u003c/p\u003e\n \u003cp\u003e(2) The influence of spatial effects on each pilot tunnel during segmented excavation;\u003c/p\u003e\n \u003cp\u003e(3) Deterioration effect of surrounding rock in post excavation pilot tunnel.\u003c/p\u003e\n \u003cp\u003eObviously, it is difficult to consider all the above factors through theoretical formulas, but in fact, the reason for the change in surrounding rock pressure can be attributed to step excavation. According to the analysis results in Section 3, it can be concluded that the first pilot tunnel is affected by the disturbance of the later pilot tunnel, and the surrounding rock pressure will continue to rise. Luo et al. constructed a surrounding rock pressure calculation method considering the mutual influence of left and right pilot tunnels based on surrounding rock pressure monitoring data, and achieved good application results [\u003cspan class=\"CitationRef\"\u003e22\u003c/span\u003e, \u003cspan class=\"CitationRef\"\u003e23\u003c/span\u003e]. The reasonable construction of an empirical model for surrounding rock pressure based on monitoring data has a good application effect on super-large-section tunnels with complex construction mechanical responses. In addition to section DK215\u0026thinsp;+\u0026thinsp;105, this article also monitored the surrounding rock pressure of the other four sections of Xiabei mountain No.2 tunnel and five sections of Xiabei mountain No.1 tunnel. Xiabei mountain No.1 tunnel is only more than 200 meters away from Xiabei mountain No.2 tunnel, and the tunnel lithology is similar to that of tunnel sections, all of which are shallow buried tunnels. Based on sufficient monitoring data, an empirical formula for surrounding rock pressure considering step excavation is constructed.\u003c/p\u003e\n\u003c/div\u003e\n\u003cdiv id=\"Sec12\" class=\"Section2\"\u003e\n \u003ch2\u003e4.2 Calculation formula for surrounding rock pressure\u003c/h2\u003e\n \u003cp\u003eBased on the calculation formula for surrounding rock pressure proposed by Wang et al., a formula for calculating surrounding rock pressure considering the influence of distributed excavation is constructed (Eq.\u0026nbsp;(\u003cspan class=\"InternalRef\"\u003e1\u003c/span\u003e)) [\u003cspan class=\"CitationRef\"\u003e30\u003c/span\u003e]. Firstly, simplify the tunnel excavated by the double-side-wall pilot tunnel method into three straight wall arched tunnels. Then, through Eq.\u0026nbsp;(\u003cspan class=\"InternalRef\"\u003e1\u003c/span\u003e) calculate the surrounding rock pressure of three pilot tunnels without the influence of step excavation. Calculate the empirical parameters of step excavation based on measured surrounding rock pressure data. The final rock pressure value can be obtained by combining the surrounding rock pressure without the influence of step excavation with the step excavation empirical parameters.

The main conclusions obtained from the study are as follows:\u003c/p\u003e\n\u003col class=\"decimal_type\"\u003e\n \u003cli\u003eWhen using the double-side-wall pilot tunnel method to excavate shallow-buried super-large-section tunnels in weak strata. The deformation and stress of the primary support of the tunnel not only go through a rapid development stage and a stable stage, but also fluctuate during step excavation and removal of temporary support. The application of feet-locking bolts and welding with steel frame effectively shares the pressure on the surrounding rock of the vault and limits the vertical settlement. Therefore, when excavating shallow-buried super-large-section tunnels in weak strata, special attention should be paid to the deformation and stress situation during step excavation construction nodes and temporary support dismantling, and the feet-locking bolts should be actively applied to optimize the primary support stress.\u003c/li\u003e\n \u003cli\u003eApplying high-strength temporary support and applying bolts to soil of unexcavated pilot tunnels can effectively reduce the impact of subsequent pilot tunnel excavation on the first excavated pilot tunnel. Temporary support can effectively assist steel frame in bearing the surrounding rock pressure of the vault. The excavation of the upper steps of main tunnel will significantly affect the surrounding rock pressure of other pilot tunnels. Due to the influence of step excavation, the trend of surrounding rock pressure changes is complex, and existing formulas for calculating surrounding rock pressure or directly calculating the weight of the overlying soil layer are difficult to meet the design and construction requirements of such tunnels.\u003c/li\u003e\n \u003cli\u003eThe position with the lowest safety factor mostly occurs in the left pilot tunnel, especially on the upper steps of left pilot tunnel. For primary support, excavation of the main tunnel and construction of the inverted arch have the greatest disturbance; for temporary support, the excavation of the main tunnel causes the greatest disturbance. It can be seen that the safety factor of excavating the first pilot tunnel is slightly insufficient due to multiple disturbances. For shallow-buried super-large-section tunnels in weak surrounding rock that adopt step excavation, the primary and temporary support of the first pilot tunnel can be enhanced, while the primary and temporary support of other parts can be appropriately reduced.\u003c/li\u003e\n \u003cli\u003eBased on the measured rock pressure data of 10 monitoring sections of the Xiabei mountain No. 1 and No. 2 tunnel, an empirical parameter was proposed using data analysis to determine the impact of step excavation. Based on this, a calculation formula for surrounding rock pressure considering step excavation has been constructed. Compared with existing methods, this formula can more accurately calculate the surrounding rock pressure of super-large-section tunnels, and can also calculate the surrounding rock pressure of each pilot tunnel. It has certain application value for shallow-buried super-large-section tunnels in weak surrounding rock using step excavation.\u003c/li\u003e\n\u003c/ol\u003e"},{"header":"Declarations","content":"\u003cp\u003eCredit authorship contribution statement\u003c/p\u003e\n\u003cp\u003e*Xiuying Wang: Writing- review \u0026amp; editing, Supervision, Conceptualization, Data curation.

The design and construction issues of super-large-sections tunnels urgently need to be addressed. The Xiabei mountain No.1 and No.2 tunnels in the Hangzhou-Taizhou Railway are typical shallow-buried super-large-section-tunnels in weak surrounding rock, and their design and construction issues are representative. Eleven monitoring sections were set up in the tunnel, including tunnel deformation, surrounding rock, shotcrete, steel frames, bolts and temporary support mechanical responses. Taking the monitoring data of the most typical cross-section as an example, the mechanical response of the support structure of a shallow-buried super-large-section tunnel was analyzed in detail. Based on previous research results, this paper discusses and summarizes the common construction problems of this type of tunnel, and puts forward corresponding suggestions. The existing formula for calculating surrounding rock pressure has poor applicability to super-large-section tunnels constructed by step excavation, resulting in conservative support parameters. Therefore, based on the monitoring values of surrounding rock pressure at 10 monitoring sections in Xiabei mountain No. 1 and No.2 tunnels, empirical parameters reflecting the impact of step excavation were summarized. Based on the Wang formula and combined with the step excavation empirical parameters, an empirical formula for the surrounding rock pressure of shallow-buried super-large-section tunnels considering step excavation was constructed. The calculated results are in good agreement with the on-site monitoring data. This study can provide a good reference for similar projects.\u003c/p\u003e","manuscriptTitle":"Support mechanical response analysis and surrounding rock pressure calculation method for a shallow-buried super- large-section tunnel in weak surrounding rock","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-01-05 09:53:25","doi":"10.21203/rs.3.rs-3820422/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"6b1e8872-7daf-407d-bb54-614c89784493","owner":[],"postedDate":"January 5th, 2024","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2024-06-13T00:28:21+00:00","versionOfRecord":{"articleIdentity":"rs-3820422","link":"https://doi.org/10.1038/s41598-024-64522-6","journal":{"identity":"scientific-reports","isVorOnly":false,"title":"Scientific Reports"},"publishedOn":"2024-06-12 00:28:20","publishedOnDateReadable":"June 12th, 2024"},"versionCreatedAt":"2024-01-05 09:53:25","video":"","vorDoi":"10.1038/s41598-024-64522-6","vorDoiUrl":"https://doi.org/10.1038/s41598-024-64522-6","workflowStages":[]},"version":"v1","identity":"rs-3820422","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-3820422","identity":"rs-3820422","version":["v1"]},"buildId":"qtupq5eGEP_6zYnWcrvyt","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
