摘　　要：碾压土石坝因其技术简单、取材方便等特点,常作为矿山开采水利工程设施的流行坝型,为避免因有色金属渗漏而导致水源污染和生态破坏的潜在风险,采取有效的防渗措施对水坝的设计与施工至关重要。旨在探讨复合土工膜防渗斜墙解决方案,通过多层次结构的组合,包括长丝无纺土工布、双糙面HDPE膜、钠基膨润土毯等,形成可靠的防渗屏障,锚固于坝脚30 m外的截渗齿槽中,通过与土体的紧密结合,成功构建有效的防渗系统,以期为类似矿山建设水利工程设施的设计与施工提供有益的经验借鉴。Due to its simple technology and convenient material selection,roller compacted earth and rock dams are often used as popular dam types for mining and water conservancy engineering facilities.To avoid the potential risks of water source pollution and ecological damage caused by non-ferrous metal leakage,it is crucial to take effective anti-seepage measures for the design and construction of dams.Aims to explore the solution of composite geomem-brane anti-seepage inclined wall,which forms a reliable anti-seepage barrier through the combination of multi-level structures,including long filament non-woven geotextile,double rough surface HDPE film,sodium based bentonite blanket,etc.It is anchored in the anti-seepage tooth groove 30 meters away from the dam foot.Through close inte-gration with the soil,an effective anti-seepage system is successfully constructed,providing useful experience and refer-ence for the design and construction of similar mining water conservancy engineering facilities.
