摘　　要：Longitudinal seismic effect of tunnel has a significant impact on structural response, and its longitudinal seismic problem can not be ignored. In order to ensure the safety of tunnel use and operation, taking a river-crossing tunnel as a supporting project, the longitudinal seismic response displacement method is used to calculate the longitudinal seismic performance of tunnel structure, and the maximum axial tension and pressure, the maximum axial tension and compression stress, the tensile force of a single bolt and the opening amount of the joint under axial force are obtained, which provides a basis for structural reinforcement and safety check, thus ensuring the safety of longitudinal seismic performance of tunnel.
