Shaking table tests were conducted to investigate the aseismic behavior and dynamic response features of an immersed tunnel model and its joints. In order to contrastively study influences of wave passage effect on soil, immersed tunnel and its joints, the uniform longitudinal seismic excitation and the longitudinal seismic excitation with wave passage effect at different apparent wave velocities were considered in tests. The results showed that under the uniform longitudinal seismic excitation, the tunnel and soil body keep a synchronous motion; when the wave passage effect is considered, the tunnel and soil body have a relative sliding; the longitudinal wave passage effect and its input direction have a larger influence on axial force, bending moment and deformation of joints; the wave passage effect makes joints’ responses tend to non-uniform distribution, so the wave passage effect should be considered in aseismic design of an immersed tunnel and its joints.
