Abstract： Based on other engineering practices, this paper took a subway station in Shenyang as the research background, utilized the finite element simulation software Midas/GTS to simulate the ground surface subsidence deformation and the lateral displacement of the pile, and analyzed the changes of foundation pit deformation in different pile spacing and different pile depth. The results show that the ground surface subsidence deformation and the lateral displacement of the pile increase with increasing of pile spacing, and they increase a little when the pile depth reduces. The impact of pile spacing is relatively larger, but the pile depth affects many aspects of building envelope.
