摘　　要：泸定水电站坝基覆盖层深达148.6 m,结构较为复杂,坝基防渗为该工程基础处理的主要技术难题,其施工难度在国内已建工程中也较为罕见。经过各设计阶段的不断深化研究,结合防渗处理的现场试验,提出了防渗墙下接帷幕的联合防渗设计方案。The rockfill dam of Luding Hydropower Station founds on 148.6m-depth overburden with complex layers. The seepage control is the key in the treatment of dam foundation, and is more difficult to construct compared with other operated hydraulic projects in China. With the researches in different design phases and the on-site tests, the combination of curtain under cutoff wall is designed for seepage control.
