摘　　要：抽水蓄能电站上水库渗漏对电站效益影响较大,因此需对上水库防渗进行研究。笔者以桂林抽水蓄能电站为例,结合可行性研究阶段的水文和地质条件,从枢纽布置、防渗效果、施工条件、技术可行性、工程投资等方面对上水库防渗处理方案进行了综合比选,最终推荐采用库周钢筋混凝土面板+库底土工膜的综合防渗处理方案。该研究成果可为类似工程库盆防渗设计提供参考。The seepage of the upper reservoir of the pumped storage power station has a great influence on the benefit of the power station,so it is necessary to study the seepage control of the upper reservoir.Taking Guilin Pumped Storage Power Station as an example,combined with the hydrological and geological conditions in the feasibility study stage,the seepage prevention treatment schemes of the upper reservoir are comprehensively compared and selected from the aspects of hub layout,seepage prevention effect,construction conditions,technical feasibility and project investment.Finally,the comprehensive seepage prevention treatment scheme of reinforced concrete panel around the reservoir and geomembrane at the bottom of the reservoir is recommended.The research results can provide reference for the seepage prevention design of similar projects.
