| 摘 要： | 针对岩坡上的高挡墙堆石混合坝——江苏宜兴抽水蓄能电站上库主坝的结构进行了静动力稳定分析．依据边界元法确定结构的动力放大系数，采用有限元分析法确定挡墙的土压力分布，从而计算挡墙的抗滑稳定性，并通过拟静力法分析堆石体的抗滑稳定．计算结果显示，该坝型的抗滑稳定安全系数满足规范要求．还提出了加强地基处理、加强下游坝面保护及增强堆石坝体的抗滑稳定能力等工程建议．

| Abstract: | Static and dynamic analysis of a special structure which consists of high concrete retaining wall and rock-fill dam is performed in this paper.The dynamic amplification factor is calculated by boundary element method.The safety factor against sliding of the retaining wall is calculated by limit equilibration method,in which the earth pressure is calculated by finite element method.The safety factor against sliding of the rock is calculated by quasi-static method.The conclusion is that the project is safe against sliding,and some advic e is given. |
