闸木水库区岩溶渗漏问题研究及坝址选择

Study on Karst Leakiness of Zhamushui Reservoir & Dam Site Selection

闸木水水利水电枢纽地处鄂西南岩溶发育地区。通过大面积地质调查和岩溶追踪测试,查清了两个比较坝址,即天仙桥坝址(下坝址)和鲁家坪坝址(上坝址)的岩溶渗漏情况。选定地质条件较优的鲁家坪为该枢纽的坝址。

Zhamushui water conservancy and hydropower project is located in karst region in south-western Hubei Province, the key factor influencing on dam site selection is karst leakiness through dam foundation, on the basis of widespread geological surveying and karst tracing test, the upper reach dam site (Lujiaping dam site) is confirmed better than the lower reach dam site (Tianxianqiao dam site).
