摘要：

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　effectis　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.　©　2018,　Editorial　Office　of　Journal　of　Vibration　and　Shock.　All　right　reserved.
