摘　　要：笔者以远安抽水蓄能电站上水库为例,将坝型和全库盆防渗形式联合比选。从大坝、库岸和库底三个方面协调考虑,笔者重点对三个组合方案进行了比较研究。通过地形地质条件、施工条件、工程技术难度、方案经济性综合比较,拟定了“混凝土面板堆石坝+库周钢筋混凝土面板+库底土工膜”组合方案,笔者的研究思路及研究成果可为其他全库盆防渗及坝型设计提供参考。Taking the upper reservoir of Yuan'an Pumped Storage Power Station as an example,this paper compares and selects the dam type and anti-seepage form for whole reservoir basin.Considering coordination from the three aspects of the dam,reservoir bank and reservoir bottom,the author focuses on a comparative study of the three combination schemes.Through the comprehensive comparison of topographic and geological conditions,construction conditions,engineering technical difficulties and program economics,the combined scheme of"concrete-faced rockfill dam+reinforced concrete panel around reservoir+geomembrane at the bottom"of the reservoir bottom is proposed.The research ideas and results can provide reference for other seepage prevention of whole reservoir basin and dam type design.
