Abstract

In order to deeply understand the loading characteristics of the subway station and summarize the factors that influence the loading of the structure,we need to adopt the method of simulation to analyze the loading of the structure.The main structure static is simulated in ANSYS using an example of interchange station which belongs to Shenyang metro. A reasonable conclusion of mechanical characteristics of the station structure is drawn by its shear diagram and bending moment diagram. The paper analyzes influence factors of the large-span subway structure under the loading combined with the predecessors' achievements.Simulation results show that the lower plate bending moment is slightly greater than the upper station structure and medium plate, the bending of medium column is very small, the bending of lower column is very large, the position of strong shear force is the same as the position of strong bending moment .The factors results show that in different soil conditions,static earth pressure has a significant impact on the side wall and has a little influence on bending moment of the board’s midspan and bearing.When groundwater reaches the top board position, static earth pressure has a greater effect on roof bending moment. In different project profile, the stress of standard combination state distribution is almost the same as the stress of basic combination.In general accident combination, the substructure doesn’t show big damage,but we should focus on special circumstances. We can conclusion that ANSYS can make a better mechanical characteristics analysis of metro station structure. And we can use ANSYS to provide reference for the future design of metro station combined with the influence factors of the structure under the loading.
