三峡工程双线五级船闸设计

The design of double line five step ship lock of Three Gorges Project

简要介绍了三峡双线五级船闸的总体设计及总体布置,高水头船闸的输水技术,全衬砌船闸结构的关键技术问题,大型人字门及启闭设备和复杂运行条件下的监控技术。船闸自2003年投入运行,运行实践证明,设计采用的技术先进、合理、可靠。三峡船闸的设计建设,发展了船闸工程的设计理论和实践,使世界船闸工程技术达到了新水平。

The general design and layout of the double-line five-step ship-lock , the water delivery tech-nique for high head ship-lock, the key technical problems of fully lined ship-lock and the monitoring techniques for large-scale miter gates and hoisting equipment under complicated operation conditions of the Three Gorges Project （TGP） are introduced. Since the operation of ship-lock in 2003, the operation practice has proved that the design techniques are advanced, rational and reliable. The design and construction of the fully lined ship-lock promotes the development of design theory and practice of ship-lock projects, which makes the construction technology of ship-lock in the world reach a new level.
