Abstract

Multiple aftershocks generally occur following a significant earthquake in a short time. When faced with aftershocks, the seismic safety reserve of underground structures will be reduced due to the accumulation of previous earthquake damages. At present, the influence of multiple aftershocks is ignored in the seismic design and performance improvement of underground structures. In this paper, the Daikai subway station during the 1995 Osaka-Kobe Earthquake was taken as the prototype and a nonlinear numerical model of soil-underground structure interaction was established based on Abaqus software. Real seismic records containing multiple aftershocks were selected and used to compare the seismic response characteristics of underground structures subjected to different earthquakes, including multiple aftershocks, single earthquake case and main shock-aftershock sequence. The results show that the seismic damage to underground structure caused by aftershocks is more serious than that caused by single earthquake excitation, and this result is not obvious when the aftershock intensity is small. The peak displacement of structures for the action of multiple aftershocks is equal or higher than that for the corresponding single earthquakes, but less than the cumulative value of a single earthquake. Moreover, the residual displacement of the middle column increases with the number of aftershocks, which is not conducive to post-earthquake structural repair.
