| 摘 要： | 西河水电站闸坝存在较为严重的库水渗漏问题。以西河水电站库水渗漏处理的全过程为例．分析了闸坝的地层、岩性、构造和水文地质条件，找到了渗漏发生的位置在左坝肩、其原因为存在溶蚀孔隙发育的顺河向透水灰岩条带．提出了渗漏处理的方案．并对灌浆处理前后的岩体的透水性进行了对比。对比资料表明：固结灌浆大幅度地降低了岩体的透水性．达到了加固岩体、减少库水渗漏的目的。

| Abstract: | Considerable reservoir seepage occurs in Xihe hydropower station . According to treatment of Xihe hydropower station , strata , rocks , tectonics and hydrogeological condition at the gate dam is analyzed and seepage occurs on the left abutment and was caused by porous limestone zone along the river . A seepage treatment measure is provided and the permeability of rock mass is compared before and after grouting . The result indicates that the permeability of rock mass is decreased by consolidation grouting and rock mass is reinforced and reservoir seepage is reduced . |
