| 摘 要： | 某抽水蓄能电站上水库主坝由于特殊的地形条件采用了高挡墙混合坝方案，本文对该坝进行了有限元动力反应分析，给出了坝体的震动响应加速度和残余变形，探讨了基岩、库水、下游坡度几个因素对坝体加速度放大系数的影响，得到了一些有益的认识。

| Abstract: | In this paper, dynamic response analysis in finite element method is carried out for a complex dam which has high retaining walls in special topographical condition.The time histories of the response accelerations of the dam and the residual deformation are obtained.The permanent deformation due to earthquake excitation is also evaluated.Special attention is paid to the influences of bedrock,reservoir water and downstream slope on the acceleration amplification coefficient. |
