Present day, excavation goes deeper and sometimes it is constructed on soft soils. Therefore, an appropriate analysis must be conducted in order to assure a safe excavation. A case study takes place in an apartment project in Central Jakarta, Indonesia. The excavation is about 12 m depth, with free-standing soldier piles protection. Soil stratification of the project consists of four layers, with 6 m of soft clay at the top layer. At the same time, the neighborhood of the project is also crowded by residential buildings. There are some soil models that commonly used in deep excavation analysis. Two of them are hyperbolic model and Mohr-Coulomb model. This paper discusses the use of hyperbolic soil model in excavation analysis using finite element method, considering the strain level. Strain level checking conducted at near of soldier piles in order to predict appropriate value of soil modulus. The use of Mohr-Coulomb model is also conducted for soldier piles deformation comparison. The soldier piles deformation profile from hyperbolic model and Mohr-Coulomb model then compared to inclinometer reading. The results show that hyperbolic soil model gives similar deformation profile, both shape and value of deformation, compared to inclinometer reading. Hyperbolic soil model is quite capable and accurate to model deep excavation problem.
