三峡工程是当代全球最大的水利工程 ,其中的每一项重大工程技术设计与施工建造 ,均可列为世界水利工程的难题和典型案例 ,是人类水利工程建设中的一笔宝贵财富.文章根据 1 994年开始的三峡通航建筑物技术设计的全面审查 ,就通航建筑物总体布置 ,船闸输水系统和船闸水力学 ,永久船闸高边坡设计 ,永久船闸水工结构 ,升船机 ,技术设计阶段的科研工作成果等 6个部分做了阐述和讨论.“,”The Three Gorges Project (TGP)is the greatest water conservancy engineering being built in the world.Each of the technical design and the engineering constuction in the project can be a worldwide key technical difficult and a representative case of water conservancy engineering. Based on the overall examination of the Three Gorges Project navigation construction technical design,which started in 1994,the following 6 topics are described and discussed:1)the general layout of the TGP navigation construction;2)lock's filling and emptying system and the lock's hydraulics;3)the design of the high slope of the permanent ship lock;4)the hydro|structure of the permanent ship lock;5)shiplift;6)scientific research and its achievement during the technical design stage.
