摘　　要：抽水蓄能电站建设进入了快速发展阶段。部分抽水蓄能电站工程采用了全库盆防渗,全库盆防渗方案主要有沥青混凝土面板全库盆防渗、库岸钢筋混凝土+库底土工膜防渗和全库盆钢筋混凝土防渗等。介绍了全库盆防渗结构中常用的3种不同防渗形式(沥青混凝土面板、钢筋混凝土面板、土工膜)的特点,对比分析3种防渗形式的主要优缺点,并探讨全库盆防渗形式选择应考虑的因素,研究对比了在相同库容条件下全库盆防渗工程防渗总面积的影响因素。The construction of pumped-storage power stations has entered a rapid development stage.Some pumped-storage power stations use the whole reservoir basin seepage control schemes,which mainly includes three different schemes of whole reservoir basin asphalt concrete face slab,reservoir bank reinforced concrete+reservoir bottom geomembrane,and whole basin reinforced concrete.Three different structure types for whole reservoir basin seepage control are introduced,including asphalt concrete face slab,reinforced concrete face slab and geomembrane,and the main advantages and disadvantages of these three seepage control types are compared and analyzed.The factors to be considered in the selection of whole reservoir basin seepage control types are discussed,and the influencing factors of total anti-seepage area of whole reservoir basin seepage project under same reservoir capacity are also compared.
