In this paper, a three-dimensional shaking table test of three three-span subway station model is done. Three test seismic waves were selected in this experiment, which were applied to the model. Modal analysis of the structure was done, and the determination of the acceleration of the model structure was obtained. And the law of underground structures under earthquake damage was analysis. Soil surface acceleration process and its response spectrum and strain are obtained in the different amplitudes of ground motion input case. From experiment cracks in the emergence and development of the situation were observed, and which gives recommendations for the seismic design of underground structures.

Shaking Table Tests

Shaking table tests were conducted on typical models of subway structures subjected to several seismic shaking time histories to study seismic response of subway structures in soft ground as well as to provide data for validation of seismic design methods for underground structure. Three types of tests were presented herein, namely green field test, subway station test, and test for joint structure between subway station and tunnel. The similitude and modeling aspects of the 1g shaking table test are discussed. The seismic response of Shanghai clay in different depths was examined under different input waves to understand the acceleration amplification feature in both green field and in the presence of underground structure. Damage situation was checked on internal sections of both subway station and tunnels by halving the model structure. Structure deformation was investigated in terms of element strain under different earthquake loadings. The findings from this study provides useful pointers for future shaking table tests on underground structures/facilities, and the seismic response characteristic of underground structure derived from the shaking table test could be helpful for validating seismic design method for subway station.
