Abstract: In this paper, the impact of TBM (shield) construction on pile foundation is studied by numerical simulation of geological conditions in a certain area of chongqing, Flac3d 3d modeling software and finite difference method. This paper also describes the simulation process of TBM (shield) construction. The research shows that TBM (shield) construction has different effects on the spacing of different piles. Based on the simulated data, it can be concluded that the vertical displacement at the top of the pile with the same root is larger.
