摘　　要：试验研究了三峡枢纽运行初期坝上游的通航条件。在枢纽运行３２年之内，坝上游修６６０ｍ短堤的引航道即能满足通航要求。在运行２０年之内泥沙淤积不会影响船闸侧向取水，２０年之后则需在取水口附近适时清淤。对坝区来沙量变化、淤积过程、挟沙能力及浓度分布等参数进行了分析。研究结果表明，大包隔流堤可以在３０年以后修建。The navigation condition of the upstream of Three Gorges Project Dam was experimentally studied for the initial period in this paper. In the period of the project operated for 32 years, the flow condition could satisfy the navigation demands only need to build 660 m short separating dike. The sediment deposition has no influence on the intake water of the ship lock within 20 years. After the project operated for 20 years, some draining sediment measures ought to be taken to guarantee the intake water. Some basic factors were analyzed such as the sediment amount coming into the dam area, the process of sediment deposition, the transport capacity of suspend load and the concentration distribution. The separating dike including the shiplift channel could be built after 32 years of the project operation.
