摘要:

There are many kinds of ground motion intensity measures that affect the dynamic response of metro stations. It is of great practical significance to study the correlation between the ground motion intensity measures and the structural seismic response indexes for seismic design of underground structures. In order to study the ground motion intensity measures suitable for evaluating subway underground stations under the near-field ground motion, the Daikai metro station is taken as the prototype. Based on the results of nonlinear time-history analysis, through the bilinear logarithmic regression analysis of 22 seismic intensity measures and structural seismic response indexes, the ground motion intensity measures and structural seismic response indexes are analyzed and evaluated in terms of efficiency, practicality and proficiency. The results show that the acceleration ground motion intensity measure represented by PGA and the spectral correlation ground motion intensity measure represented by ASI are more suitable for studying one-story subway station structures, which are suitable for predicting the dynamic response of structures under ground motion. The drift ratio between the top slab and the bottom slab, the shear force at the bottom of the middle column and the bending moment at the bottom of the middle column are suitable as the dynamic response indexes for predicting the underground subway structures. © 2020, Editorial Office of Chinese Journal of Geotechnical Engineering.
