岩溶地区利用天然坝体修建水库的尝试——以孔梁水库为例

岩溶地区修建水库的弱点主要是成库条件差,难点在于水库渗漏问题的解决.但是,岩溶地区也存在许多得天独厚的天然坝体,采取封堵地下溶洞等工程措施便可形成一定规模的水库.孔梁水库工程采用堵洞成库措施,实施了岩溶地区利用天然坝体修建水库的尝试,以较少的投资获得较好的社会效益和经济效益.

Trial of constructing reservoir with natural dam in karst region: a case of Kongliang Reservoir

The major weakness of constructing a reservoir within karst region is poor condition for reservoir-forming with the difficulty of how to solve the problem of seepage. However, a lot of advantaged natural dams are there in karst regions; with which a certain scales reservoirs can be constructed by blocking up the underground karst caves therein. A trial to constructing reservoir with natural dam within karst region is made with the case of Kongliang Reservoir Project which is constructed with the measure of forming reservoir by cave-blocking, and then better social and economic benefits has been obtained with less investment.
