ABSTRACT
In recent years, the safety of the structure of subway stations, as the transit center of urban rail transportation, has become a key research direction. Most urban areas in China are in seismic zones, and earthquakes are one of the main factors causing the destabilization of underground structures. In order to investigate the dynamic response of conventional subway stations under the action of seismic waves in different directions, a box-type subway station is used as the research object, and finite element dynamic time analysis is used to investigate the seismic response of subway stations under horizontal, vertical and horizontal-vertical coupled action of seismic waves. The results show that the horizontal seismic wave input has a large effect on the seismic response of the structure and the structure has good vertical seismic performance.
