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1994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.
