五岳抽水蓄能电站上水库防渗型式比选研究

Comparison and Selection of Seepage Control Mode for Upper Reservoir of Wuyue Pumped Storage Power Station

笔者结合五岳抽水蓄能电站上水库水文条件及工程地质条件,参照国内外抽水蓄能电站建设实践经验,对上水库防渗型式拟定垂直防渗方案、全库盆防渗方案和综合防渗方案3个比选方案,通过防渗效果、工程技术难度、施工难度及工期、工程投资、防渗体耐久性、方案经济性等方面综合比较,最终采用垂直帷幕的防渗设计方案,其研究思路及研究成果可为类似工程建设提供参考。

Based on the hydrological conditions and engineering geological conditions of the upper reservoir of Wuyue Pumped Storage Power Station,and referring to the practical construction experience of pumped storage power station at home and abroad,the author proposes three schemes for the seepage control of upper reservoir,they are vertical seepage control scheme,whole reservoir basin seepage control scheme and comprehensive seepage control scheme.Through comprehensive comparison of anti-seepage effect,engineering technical difficulty,construction difficulty and construction period,project investment,impermeable body durability and scheme economy,the seepage control design scheme of vertical curtain is finally adopted.The study ideas and results can provide reference for similar engineering construction.
