摘　　要：围堰是输水隧洞工程中的关键部分,可对工程水土进行有效控制以满足整体工程建设需求。基于此,以实践案例为基础,通过导流计算和导流建筑物结构的稳定性分析,保障围堰设计的合理性,并提出防泥幕、土石方开挖与填筑、沟槽混凝土、复合土工膜心墙、围堰拆除等环节的施工方案,以确保输水隧洞进口围堰工程质量。The cofferdam is a key part of the water conveyance tunnel project,which can effectively control the soil and water of the project to meet the overall construction needs.Based on this,taking practical cases as the basis,the rationality of the cofferdam design is ensured through diversion calculation and stability analysis of the diversion building structure.Construction details such as anti-mud curtain,earthwork excavation and filling,trench concrete,composite geomembrane core wall,and cofferdam removal are proposed to ensure the quality of the water conveyance tunnel inlet cofferdam project.
