摘　　要：西北地区某注入式水库因地质条件所限,库盘透水性好,水库常年渗漏,损失巨大。对水库地质环境进行分析论述,并对库盘表层粉土和卵石混合土进行颗分试验,得到库盘漏水的形式和水量。采用有限元方法对粘土铺盖防渗和复合土工膜防渗两种方案进行二维渗流分析,得到复合土工膜防渗方案在有效降低全库渗流量的同时利于大坝稳定的结论,可为类似工程提供参考。Due to the limited geological conditions,an injection reservoir in the northwest region has good water permeability,and the reservoir leaks all the year round,resulting in huge losses.The geological environment of the reservoir is analyzed and discussed,and the silt and pebble mixed soil on the surface of the reservoir is subjected to a granulation test to obtain the form and volume of water leakage in the reservoir.The finite element method is used to analyze the two-dimensional seepage flow of the clay cover anti-seepage and composite geomembrane anti-seepage schemes,and the conclusion that the composite geomembrane anti-seepage scheme can effectively reduce the seepage flow of the whole reservoir is beneficial to the stability of the dam,which can be similar The project provides reference.
