摘　　要：针对某水利枢纽工程大坝渗漏问题,采用溶质示踪方法对该水库渗漏位置进行检测并进行结果分析,根据分析结果给出相应水库防渗处理措施。结果表明:左坝肩心墙上游与下游近10m高程有较强渗漏;右坝肩下覆砂层形成渗漏通道;左右坝肩局部存在较强的绕坝渗漏;坝脚处浅层地下水整体流向为自东向西,流速较大。According to the seepage problem of the dam for some a hydro-junction project, the solute tracer method is used to test seepage position and to analyze the results. Based on the analysis results, the corresponding treatment measures of reservoir seepage control are put forward.The results show that there is strong seepage near10 m elevation in the upstream and downstream of the left abutment wall, there is a leakage path formed in the sand layer under the right abutment, there is a strong seepage around dam in the part of the dam abutment, the global flow direction of shallow groundwater is from east to west and the speed of flow is larger at the toe of dam.
