Numerical Analysis of Foundation Soil Displacement to Adjacent Buildings Caused by Running Subway

Abstract

The tunnel - subgrade - adjacent buildings interaction model was established by ANSYS to simulate the soil displacement by Running Subway to adjacent buildings. According to D'Alembert principle, we got the dynamic load produced by train acceleration. Multi-point load was applied to simulate the movement of train. Based on ANSYS simulation results, the surrounding soil displacement of the tunnel was analyzed when in different train speed. On the other hand, the soil displacement in different depths is analyzed when in the same train speed.
