Pipe jacking slurry, as the primary measure for friction reduction and strata support, is crucial to ensuring the safe execution of pipe jacking construction. This paper introduces the microbial-induced calcium carbonate precipitation (MICP) technology into the field of pipe jacking slurry to improve its friction-reducing effect and enhance soil stability. To achieve this, the optimal mix ratio of MICP-slurry was selected through the uniform design method. Model tests were conducted to investigate the friction-reducing effect of MICP-slurry, and the mechanism of MICP-slurry in strengthening strata stability was analyzed through mechanical tests and scanning electron microscope (SEM) tests. The results show that the optimal mix ratio of MICP-slurry is bentonite: CMC: soda ash: PAM: xanthan gum = 12%: 0.31%: 0.36%: 0.25%: 0.54%. MICP-slurry reduces the friction coefficient between the test block and sand by 42.2%. Compared to the untreated sample S-1, the cohesion and internal friction angle of the MICP-treated sample S-2 increase by 38.12% and 14.01%, respectively. SEM analysis reveals that the calcium carbonate crystals induced by MICP-slurry in the soil fill the pores, enhance the bite force between soil particles, and improve the mechanical properties of the soil.
