摘　　要：那比水电站已建成并运行多年,大坝坝内廊道的渗漏水孔发现有米白色和黑褐色的析出物,并有两处渗漏水水流明显,为研究其对大坝安全的影响、判断环境水质是否对混凝土存在侵蚀,对那比水电站库水、廊道渗漏水水质及析出物进行了成分分析,总结了析出物的成因和各成分对大坝的影响,为大坝的安全运行提供了试验依据。Nabi Hydropower Station has been constructed and put into operation for many years.White and dark brown precipitates from the leakage holes and two obvious leakage water flows have been found in the galleries in⁃side main dam.In order to study its impact on the dam safety and determine whether the environmental water quality has an erosive effect on the concrete,the composition analysis was carried out on the reservoir water,the leakage wa⁃ter and the precipitates from the galleries of Nabi Hydropower Station.The causes for the precipitates and the impact of each component on the dam were summarized,providing an experimental basis for the safe operation of the dam.
