Abstract	Based on the character of typical foundation pit support structure and method in gravel stratum, by establishing reasonable 3-D seismic response analysis numerical simulation, adopting LS-DYNA software, this paper studied the stability and disability mutation process of foundation pit and support structure under intense earthquake action. The results show that vibration-resistence character of bolt-shotcrete is better than that of steel support; vibration displacement and unstable failure of steel support have significant time domain characteristics, and failure happens in very short time; propagation direction of the seismic wave has a great influence on the structure stability. The research results provide reference for construction safety and construction technology of foundation pit in frequent earthquake occurrence area.
