摘　　要：水库渗漏问题既影响水资源的利用,又威胁水库的安全运行,是水库工程中的典型问题之一。为探究陕西山阳抽水蓄能电站下水库渗漏问题,以区域地质与水文地质条件为基础,结合地质钻探、压水试验等结果,分析了下水库的渗漏模式,得出下水库存在坝基渗漏和右坝肩绕坝渗漏问题,并通过解析法和数值法估算渗漏量,采用解析法估算出渗漏量为1054m^(3)/d,数值法得到的渗漏量为1783m3/d,得到渗漏量占总库容的0.020%~0.034%,小于总库容的0.05%,符合建库规范要求。The problem of reservoir leakage not only affects the utilization of water resources,but also threatens the safe operation of reservoirs.The problem of leakage is one of the typical problems in the reservoir engineering.In order to research the leakage of the lower reservoir of Shanyang Pumped Storage Power Station in Shaanxi Province,the regional geological and hydrogeological conditions was firstly studied.Then the geological drilling,water pressure tests and other results were analyzed to obtain the leakage mode.The results show that there is leakage at the dam foundation and the right abutment.The amount of leakage was estimated with the analytical and numerical simulation methods.The evaluated leakage amounts are about 1054m3/d with the analytical methods and 1783m3/d with the numerical simulation method.The amount of leakage accounts for about 0.020%~0.034%of the total storage capacity,which is less than 0.05%of the total storage capacity.The results of this study show that the leakage amount meets the requirements of the reservoir construction specifications.
