Study on Effect of Seismic Joint to Seismic Response of Tunnel Passing through Fault

Abstract:

As underground structure, the tunnel itself has good anti-seismic performance, but in recent years, according to a large number of investigation data about the earthquake disaster for tunnel, we find that the tunnel passing through the fault fracture zone is quite easy to be destroyed seriously. Therefore, developing dynamic response analysis and shock absorption measures has great practical significance. According to the characteristics of tunnel passing through fault and the tunnel depth, considering a certain proportion relationship in finite element model, the analysis model for tunnel seismic joint is established. Finally comparing the results comprehensively, we discuss the effect of the different setting location and setting separation distance of seismic joint to seismic response of tunnel passing through fault. From the work we have done, we get the seismic joint which is good for tunnel seismic resistance. This method is expected to be adopted as reference to the similar projects.
