Abstract

Abstract

Taking the bilateral deep foundation pit construction in some soft soil area adjacent to the subway station and shield tunnel as an example, using the numerical calculation software ABAQUS to carry out the numerical simulation of bilateral deep foundation pit construction, The influence of the construction process on the soil uplift in the foundation pit and the soil settlement outside the pit is studied, the deformation conditions of the subway station and shield tunnel were analyzed and the regularity were obtained. The calculation results show that the maximum value of soil uplift inside the foundation pit is 54.3 mm. The maximum x-direction displacement of the surrounding structure is 32.8 mm and the maximum y-direction displacement is 26.8 mm. The maximum vertical displacement of the station occurs from excavation to pit bottom in area A1, with a maximum value of 6.8 mm, while the maximum horizontal displacement of the station is 7.6 mm. The maximum cumulative increment of bending moment is 155.9 kN·m/m. The maximum x-directional horizontal displacement of shield tunnel is 4.7 mm. The maximum settlement value of shield tunnel is 3.8 mm, which occurs when the tunnel is excavated from area A1 to the bottom of the pit.
