Seismic Response Analysis of the Transfer Station in Transportation Junction Considering the Effect of the Pile and Soil

In order to understand the seismic performance of the large complex structure with multi-storey basement, the structure-pile-soil finite element model of a typical cross sections of one transfer station in a transportation junction were established by using the ANSYS software. The time history analysis was adopted, and the seismic responds of the whole system under the seismic load was analyzed, and some rules were attained. Comparing the result of the seismic responds with the rigid foundation model which the soil around the underground structure simulated by spring element, and some salutary conclusions are attained.
