丹巴水电站是大渡河干流水电规划“三库22级”的第8级电站,左右两条引水隧洞长10余公里,调查揭示沿线地下水丰富,本文即是通过对隧洞线泉水水样进行采样、水质分析结果讨论其对隧洞中的混凝土砌体的影响。结果表明隧洞经过区基岩地下水水质不会对衬砌混凝土造成不利的影响。只是佛爷崖断层带处地下水硫酸根离子含量较高,存在一定的酸性侵蚀作用。 Danba Hydropower Station is the Dadu River Hydropower Planning “Sanku 22 ” level 8 power station, about two diversion tunnel length of more than 10 kilometers, the survey revealed that the groundwater along the rich, this article is through the tunnel spring water samples Sampling, water quality analysis results discuss its impact on the concrete masonry tunnel. The results show that the groundwater quality of bedrock passing through the area will not adversely affect the lining concrete. However, the content of sulfate ion in the groundwater at the Foyeya fault zone is higher, and there is a certain acid erosion effect.
