摘　　要：沂水河为淮河水系颍河的支流,沂水河渠道倒虹吸工程区上游集流面积86.60 km^(2)。工程场区为土、岩双层结构,上覆第四系黄土状轻、中、重粉质壤土和粉质粘土,下伏上第三系粘土岩、砾岩,主要存在施工边坡稳定及基坑排水问题。分析南水北调中线一期工程总干渠沂水河渠道倒虹吸工程地质问题,评价其对工程设计、施工及管理的重要意义。Yishui River is a tributary of Yinghe River in Huaihe River system.The upstream collecting area of Yishui River channel inverted siphon engineering area is 86.6 km^(2).The engineering area is a double-layer structure of soil and rock,overlying with Quaternary loess which consists of light,medium and heavy silty loam and silty clay,and underlying with tertiary claystone and conglomerate.There are mainly problems of slope stability and foundation pit drainage in the engineering area.This paper analyzes and evaluates the problems of inverted siphon in Yishui River,which is in the main channel of the first phase of the middle route of the South-to-North Water Diversion Project,and evaluates its significance to the design,construction and management of the project.
