摘　　要：溧阳抽水蓄能电站地形地质条件特别复杂,以Ⅲ、Ⅳ类围岩为主,局部为Ⅴ类围岩。选择了符合工程实际的坝型和枢纽布置方案,对电站上水库、输水系统、地下厂房、下水库设计中的关键技术问题,如大跨度地下厂房洞室围岩稳定、复杂料源高面板堆石坝填筑、库底回填全库盆防渗、大PD值引水钢岔管设计、竖井式进出水口设计等,进行了系统研究,并确定了合理的技术方案。The topographic and geologic conditions in Liyang Pumped-storage Power Station are particularly complex, in which the surrounding rocks are mainly classified as Class III and IV, and local as Class V. The dam type and structure layout are selected in accordance with the actual conditions of power station. The key technical problems in the design of upper reservoir, water delivery system, underground powerhouse and lower reservoir, such as the stability of surrounding rocks of large-span underground powerhouse cavern, the filling of high CFRD with complex material source, the backfilling of reservoir basin bottom and basin seepage control, the design of diversion steel bifurcation with high PD value and the design of shaft-type inlet/outlet, are systematically studied, and the reasonable technical solution are finally determined.
