Numerical Simulation of Subway Station Constructed Using Top-Down Method

Abstract:

This paper mainly deals with the stress and deformation behavior of the subway station structure during the excavation, the construction of the station constructed using top-down method is simulated with ANSYS. The research results show that the diaphragm wall, column and horizontal plate uplift and sink alternately under the influence of foundation rebound, gravity and construction load. Under the influence of lateral soil pressure and horizontal plate, the horizontal deformation curves of the diaphragm wall is similar to bow at first and then to s shape. The huge horizontal stiffness of the plate can control the horizontal deformation of the diaphragm wall effectively. The most disadvantageous positions of internal force in each condition are shown finally, and the results can be referenced by similar engineering.
