摘要：The general design and layout of the double-line five-step ship-lock,the water delivery technique 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 Three Gorges Project (TGP) are *** the operation of ship-lock in 2003,the operation practice has proved that the design techniques are advanced,rational and *** 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.

摘要：随着经济的发展,三峡船闸过坝运量急速增长。由于三峡大坝下游部分航道通航条件无法达到规划的一级航道标准,导致过坝船舶的组成、尺度与船闸难以匹配,船闸通过能力无法充分发挥,致使闸前偶有压船现象。有针对性、有计划地对尚未达到一级航道的河段进行治理,使过坝船舶的组成、尺度与三峡船闸的有效尺度相匹配,同时进行科学调度,是充分发挥三峡船闸通过能力的根本途径。

摘要：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。
