摘　　要：翁涧河渠道倒虹吸渠工程为南水北调中线工程总干渠穿越翁涧河的河渠交叉建筑物,工程区地质结构类型为粘砂多层结构,主要存在工程地质问题、闸基稳定问题、施工边坡稳定、施工排水问题及承压水的顶托破坏问题等。文章针对工程区主要工程地质问题结合建筑物类型、工程水文地质条件进行分析评价,提出了合理的处理建议,对太行山前冲洪积平原区倒虹吸建筑物工程设计、施工及工程运行管理具有指导意义。The wengjian river channel inverted siphon channel project is a river channel crossing structure where the main canal of the Middle Route Project of South to North Water Transfer crosses the wengjian river.The geological structure of the project area is a clay sand multi-layer structure,mainly including engineering geological problems,gate foundation stability problems,construction slope stability,construction drainage problems and jacking damage of confined water.,etc.This paper analyzes and evaluates the main engineering geological problems in the combination of building type and engineering hydrogeological conditions,and puts forward reasonable suggestions,which has guiding significance for the engineering design,construction and engineeringoperation management of inverted siphon buildings in the alluvial plain area in front of Taihang Mountain.
