摘　　要：自尼尔基水利枢纽建成蓄水以来,随着水库水位的升高,左副坝下游渗水量较大,由于坝后渗水未设置排水通道,致使下游排水棱体处开始有较大面积积水,浸没影响问题日渐突显。文中在分析渗漏原因的基础上提出了修复处理措施,并对渗漏排水处理工程进行了后期监测,证明工程对坝下浸润线的降低起到了一定的作用。Since the Nierji hydro-junction has been built, the downstream of the left auxiliary dam has the large leakage with the rise of the reservoir water level. Because of the lack of drainage channel for the downstream leakage of dam, the downstream drainage mound position of dam has the water accumulation with the larger area, and the problem of immersion has become increasingly prominent. Based on the analysis of leakage causes, the paper puts forward the remediation measures and the post-construction monitoring of the leakage drainage treatment project is carried out, it is proved that the project has play a certain role in reducing the dam saturation line.
