Critical　for　the　seismic　safety　of　immersed　tunnels　is　the　magnitude　of　deformation　and　force　developing　in　the　segment　joints.　To　investigate　the　seismic　performance　of　segment　joint　in　immersed　tunnel,　this　paper　presents　a　series　of　shaking　table　arrays　tests　that　were　performed　on　a　microconcrete　tunnel　model　embedded　in　the　soil.　The　tests　take　account　of　the　uniform　and　wave　passage　effect　in　different　apparent　wave　velocity　of　longitudinal　seismic　excitation.　The　result　showed　that　the　wave　passage　effect　had　a　great　impact　on　axial　force,　bending　moment　and　deformation　of　joints.　The　comparison　showed　that　structural　response　under　nonuniform　earthquake　excitation　is　larger　than　that　under　uniform　excitation.　The　simplified　model　was　established　in　ABAQUS　for　numerical　analysis.　The　soil　around　the　tunnel　was　simplified　as　spring-damper,　the　tunnel　was　simplified　as　beam　element,　and　the　joint　was　simulated　by　nonlinear　spring.　The　numerical　simulation　results　were　in　good　agreement　with　the　experimental　data.　In　addition,　the　model　was　analyzed　by　changing　input　apparent　wave　velocity,　joint　stiffness　and　joint　number.　The　results　showed　that　the　deformation　of　joints　was　smaller　and　the　deformation　of　flexible　joints　was　greater　under　high　apparent　wave　velocity.
