摘　　要：抽水蓄能电站上水库在西南喀斯特地区建库面临显著技术挑战。笔者以贵阳抽水蓄能电站上水库为典型案例,基于岩溶地质特征,系统开展坝址坝型比选、库轴线优化及防渗方案论证:首先通过综合比选确定库址Ⅱ为推荐坝址;其次从地形适应性、工程量及投资角度遴选出最优库轴线方案;最终结合防渗性能、经济性与施工可行性,选定“沥青混凝土面板堆石坝+全库盆防渗”的方案。研究成果可为喀斯特地区水库建设的坝址优选、工程布局及防渗设计提供重要技术参考。The construction of upper reservoir for pumped storage power station in southwest karst area faces significant technical challenges.Taking the upper reservoir of Guiyang Pumped Storage Power Station as a typical case based on the karst geological characteristics the dam type comparison reservoir axis optimization and anti-seepage scheme demonstration are systematically carried out.Firstly the reservoir siteⅡis determined as the recommended dam site through comprehensive comparison Secondly the optimal reservoir axis scheme is selected from the perspective of terrain adaptability engineering quantity and investment Finally combined with the anti-seepage performance economy and construction feasibility the scheme ofasphalt concrete face rockfill dam+whole reservoir basin anti-seepage is selected.The research results can provide important technical reference for dam site optimization engineering layout and anti-seepage design of reservoir construction in karst area.
