摘　　要：水库坝基防渗直接关系到坝体安全性能和水库作用效能,而土工膜全库盘防渗技术由于投资成本低、防渗效果好、施工简单等优点得到了广泛应用。小泉水库地层渗透性较强,水资源浪费严重,设计采用土工膜全库盘防渗处理。经数值模拟分析,小泉水库库盘和坝基会产生的最大应变值为17.10cm,对土工膜要求的容许拉应力为0.065MPa;试验室分析得出所用复合土工膜容许拉应力为1.00MPa,容许应变值为5.16m,安全系数均在10以上,完全满足使用要求。The seepage control of reservoir dam foundation is directly related to dam safety performance and reservoir efficiency, and geomembrane full panel anti-seepage technology has been widely applied for its low investment cost, good seepage control effect and simple construction. The formation of the reservoir in the Xiao Quan reservoir is strong and the waste of water is serious. The design of the geomembrane is used to prevent the seepage of the whole reservoir of the geomembrane. By numerical simulation, the maximum strain of the reservoir and dam foundation plate Koizumi will produce a value of 17.10 cm, the allowable tensile stress of 0.065 MPa geomembrane requirements; laboratory analysis of the composite geomembrane allowable tensile stress is 1.00 MPa, the allowable strain value is 5.16 m and the safety coefficient was above 10, completely to meet the use requirements.
