| 摘 要： | 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。

| Abstract: | Danba Hydropower Station is one among of the main stream of water and electricity planning. The two long diversion tunnels of the station are more than 10 km long. Quality analysis of the water samples from the tunnels showed that the water quality will not adversely affect on concrete lining of the station. The underground water samples from Buddha cliff fault showed the higher levels of sulfate ions, which would be a certain degree of acid erosion. |
