在岩溶地区迠设水电站最主要的地质问题是岩溶渗漏问题,它关系到工程的造设速度、成败和效益,故勘查研究岩溶渗漏问题具有特别重要的现实意义。大化水电站是在红水河上首先开发的一个梯级大型水电站。电站水库区出露的地层主要为上泥盆统、石炭系、及下二迭统的碳酸盐岩类,而上二迭统、中下三迭统的硅质岩、泥砂岩、泥灰岩类,仅分布在坝址附近及右岸分水岭地区。构造上处于广西“山”字型构造前弧西
The most important geological problem of hydropower stations in karst areas is the karst seepage problem, which is related to the construction speed, success and failure of the project. Therefore, the exploration and study of karst leakage has a particularly important practical significance. Dahua Hydropower Station is the first large hydropower station developed on the Red River. The strata exposed in the reservoir area of the power station are mainly Upper Devonian, Carboniferous and Lower Permian carbonate rocks, whereas the Upper Permian, Middle-Lower Triassic chert, siltstone, Rocks, only distributed in the dam site and watershed watershed.
