Abstract:Research purposes: This paper researches the dynamic response of a soil - structure system of one subway station under the seismic load with ANSYS software and analyzes the issues on establishment of the system interaction model for the soil structure, the determination of the model parameters and the setting up of the artificial boundary condition to seek the internal force and deformation behaviors of the subway station under seismic action.
Research conclusions : (1) The characteristics of the dynamic response of underground structure was associated with the soil characteristics. The horizontal deformation of the underground structure was limited by the soil, with its movement with the soil and a little variation along the structure height. (2) The moment of the outside component was larger because of the direct contact with the soil. (3)The earthquake can increase the moment and the shearing force to the middle column significantly, so the column would be more easy to be damaged. (4)The results can provide reference to the seismic design of subway station or other underground structure.
