| 摘 要： | 规划中的某水电站位于碳酸盐岩地区,库区碳酸盐岩类岩石分布面积占总面积的80%以上,岩溶发育,水文地质条件复杂,岩溶渗漏是制约电站能否兴建的关键问题。为了探测其地下水和隐伏岩溶的空间分布情况,应用EH4大地电磁测深系统进行了勘察工作,圈定了10个岩溶和3条断裂,获得了库区的地下水和岩溶的空间分布形态。基本查明了电站水库溶渗漏问题,为电站兴建提供了依据。

| Abstract: | An hydropower station is located in carbonate rock area. Where Karst strongly develops, hydrogeologic conditions are extremly complex. The Karst seepage is the key issues which restrict the construction of the hydropower station. In order to detect the distribution of groundwater and concealed karst, the authors used EH4 magnetotelluric sounding system for the survey work. And the authors had detect 10 Karst and three faults. At the end of the paper, the conclusion was put forward that the reservoir will success after the karst leakage locations be well treated. |
