Abstract

Abstract: The seepage problem of thick permeable stratum in plain reservoir construction site can be effectively solved by using geomembrane seepage prevention technology. Taking Xixia reservoir expansion project as an example, the PE geomembrane thickness analysis, scheme optimization and leakage analysis are carried out for the separated seepage prevention structure—300 g filament needle-punched non-woven geotextiles ＋ 0.8 m PE geomembrane ＋ 300 g filament needle-punched nonwoven geotextiles at reservoir bottom.The results can provide reference for application of geomembrane seepage prevention technology in similar projects.

Key words: plain reservoir, geomembrane, seepage prevention system

摘要： 平原水库建设场地存在厚层、强透水地层，采用土工膜防渗技术可有效解决水库渗漏问题。以西夏水库扩容工程为例，对库底防渗结构为300g 长丝针刺无纺土工布＋0.8 mm 厚PE 膜＋300g 长丝针刺无纺土工布的分离式防渗方案进行了PE 膜厚度分析、方案比选和渗漏估算，可为今后平原水库土工膜防渗技术在类似工程中的应用提供借鉴和参考。
