Seismic Response and Failure Mechanism of the Subway Station: A Literature Review

Abstract

Because of the surrounding soil around the subway station, it is generally believed that the aseismic behavior of the underground subway station is so good that research on the seismic response of the underground structures is of no use. However, in 1995, Daikai subway station was the first large-scale underground structure that almost collapsed in the earthquake, which aroused people’s attention to the aseismic design of the underground structures. In this paper, a systematic summary of the seismic response research about the subway stations was proposed as a reference for researchers based on several documents. The effects of the earthquake, geological condition and structural characteristics on the earthquake damage of Daikai subway station were summarized. In addition, some suggestions we are put forward for the further study of the seismic response and failure mechanism of the subway station. Finally, some measures for the isolation and shock absorption were proposed.
