摘　　要：碳酸盐岩地区修建水库,岩溶渗漏是首要的工程地质问题,直接决定了是否可以建库以及水库效益。以大兴水利枢纽工程为例,对成库条件进行了勘察评价。勘察期间,运用勘探及岩溶调查等方法,对该地区碳酸岩岩溶发育规律及地下水水文地质问题进行研究,从而得出水库正常蓄水位下该水库不存在邻谷渗漏、库首经工程处理不会发生集中渗漏的结论。If a reservoir is proposed to be constructed in a carbonate rock area,the first engineering geological problem to be considered is karst leakage,it directly determines whether the reservoir can be built and its benefit.This text makes an investigation and evaluation on reservoir construction conditions by taking Daxing reservoir as an example.During the investigation,it uses the exploration and karst investigation methods to study the development law of carbonate rock karst and hydrogeological problems of groundwater in the area,and then draw the conclusion that there is no neighbor valley seepage under normal water level of the reservoir,and concentrated leakage will not occur at the head of reservoir after engineering treatment.
