Abstract: The upstream filling area of upper reservoir rockfill dam of Xiamen pumped storage power station makes use of weak weathering materials excavated from reservoir basin, while the downstream filling area uses fully weathered material excavated from reservoir basin. There are some differences with the compression modulus of upstream and downstream filling area due to different materials. Key technologies such as adjusting the interface angle of filling area and setting transition zone are proposed. As well, three dimensional finite element stress and strain analysis is performed, whose result shows that the deformation coordination and stability of the dam can be guaranteed.

Key words: concrete face rockfill dam, fully weathered, excavated material, dam section, dam material design, static and dynamic force analysis

摘要： 厦门抽水蓄能电站上水库面板堆石坝上游填筑区采用库内石料场开采的弱微风化料，下游填筑区利用库盆剥离的全风化土料，上、下游填筑区由于料源组成不同存在一定的压缩模量差，设计采取了调整填筑区分界面倾角、设置过渡区等关键技术工程措施，并进行了三维有限元应力应变分析计算，成果表明，可保证大坝的变形协调及安全稳定性。
