湖北省咸丰县龙洞湾水库岩溶渗漏分析

Analysis on Karst Seepage of Longdongwan Reservoir in Xianfeng County,Hubei Province

咸丰县龙洞湾水库地处鄂西南复杂的岩溶地区,水库区岩溶渗漏是直接影响工程规模和工程成败的关键问题,针对库区左、右岸河间地块和水库下游岩溶渗漏问题开展大面积的岩溶调查,并采取多种勘探手段和方法,从岩溶水系统的分析与研究着手,探明岩溶发育规律,查清水库岩溶渗漏问题,为水库成库提供了依据。

Longdongwan Reservoir is located in the complex karst region, southwestern Hubei Province, the karst seepage in the reservoir area is the key to directly affect the engineering scale and success. In view of karst seepage problems, a large area of karst investigation has carried out in the interchannel area of left and right bank, and downstream of the reservoir by means of a variety of investigation methods, starting from the analysis on karst water system, the authors find out the law of karst development, and karst seepage problems of the reservoir,which provide the basis for constructing reservoir.
