Abstract: The subway station is an important joint of the whole city subway system, its procedure of recovery from earthquake would extremely impact the resilience performance of the whole city subway system. However, the post-earthquake repair of underground subway station is difficult, time-consuming, and costly commonly, the present seismic resilience assessment method based on superstructure could not apply to the underground structures. Thus, this paper based on the former fragility research of DAIKAI station, introducing the correction factor λ_{L, i} of economic loss under different seismic performance levels and the correction factor λ_t of recovery time to consider the particularity of post-earthquake repair of underground station, which improved the resilience assessment method of underground station structure, discussing the influence of recovery function and ground motion intensity on the resilience of underground station structure, comparing to the actual data of post-earthquake damage and repair of DAIKAI station. The results indicated that the improved resilience assessment method considering the particularity of economic loss and repair time can assess the resilience loss of the underground station structure accurately. The resilience loss of the station with rapid recovery strategy (exponential recovery) is the least. Besides, this paper defined the limit recoverable ground motion intensity to ensure the function of the station would not totally loss, the results predicted the limit recoverable ground motion intensity of DAIKAI station is 0.625g.
