摘要：

In　order　to　discuss　the　dynamic　deformation　characteristics　and　evaluate　the　seismic　performance　and　dynamic　response　of　interaction　system　including　lock　chamber-soil　foundation,　both　response　spectrum　and　time-history　analyses　of　chamber　lock　interaction　system　subjected　to　horizontal　and　vertical　seismic　action　are　conducted　respectively　by　using　subspace　iteration　method　to　obtain　natural　frequencies　and　modes,　and　solving　dynamic　equations　by　Newmark＇s　implicit　method　with　considering　geometric　nonlinearity　based　on　the　computational　FEM　model.The　numerical　results　show　that　the　maximum　horizontal　displacement　of　lock　chamber　and　the　maximum　tensional　stress　are　42.5　mm　and　1.39　MPa　respectively.It　can　be　concluded　that　the　results　from　response　spectrum　and　step-by-step　integration　methods　accord　with　each　other　well　and　meet　the　requirements　of　the　seismic　code.　©　2017,　Editorial　Department　of　Journal　of　SJZU.　All　right　reserved.
