摘      要：Pushover analysis is common because of its conceptual simplicity and computational attractiveness in computing seismic *** that traditional pushover analysis is restricted in underground structures due to the stark differences in the seismic response characteristics of surface structures,this paper proposes a pushover analysis method for underground structures and its application in seismic damage ***,three types of force distribution are presented based on ground response ***,the target displacements and analysis models are established according to force-based and performance-based ***,the pushover analysis procedure for underground structures is ***,the applicability of pushover analysis to underground structures is verified by comparing the responses of a Chongwenmen subway station determined by the proposed procedure and by nonlinear response history *** addition,two other points are made:that the inverted triangular distribution of effective earthquake acceleration is more practical than the other two distributions,and that performance-based design is more effective than force-based ***,a cyclic reversal loading pattern based on one cycle of reversal loads as an earthquake event is presented and applied to the seismic damage assessment of underground *** results show that the proposed pushover analysis can be effectively applied to the seismic design and damage assessment of underground structures.
