特殊地形地质条件下筑坝方案比较

Comparison of dam construction schemes under adverse topographic and geologic conditions

摘要: 用三维弹塑性有限元和有关的稳定分析方法 ,对某抽水蓄能电站水库的混凝土面板堆石坝和混合坝两种坝型的应力变形性状、坝体沿建基面和坝基软弱地质结构面的滑动稳定性进行了分析 ,并建议采用混合坝坝型

Abstract: Based on 3-D finite element elasto-plastic calculations and some stability analytical methods, the stress, deformation and sliding stability of the pumped storage hydroplant dam with two types, namely concrete face rockfill dam and composite dam, are analyzed and compared . The results show that the composite dam is better.
