Abstract Based on an experimental study using a shaking table model for a tunnel passing through faults, this paper analyzes the tunnel's dynamic response law, studies the lining cracking process and failure mode, and discusses the damping effect of a buffer layer. The results show that the seismic response of a tunnel passing through faults has the characteristics of asymmetry and a hanging wall effect, while the overall seismic performance is improved significantly; the lining is stressed uniformly both horizontally and vertically with the installation of the buffer layer. Especially for the invert, the tension stress state is greatly improved. The test results provide a reference for aseismatic tunnel design, post-disaster reconstruction, and the revision of corresponding codes in the future.
