摘要
三峡永久通航船闸设计总水头113米,是目前世界上设计总水头最高的大型船闸。多年来对船闸的水级划分和线路位置进行了多方案研究,经着重对连续式5级船闸和分散式带中间渠道的3级船闸两种布置方案进行专题论证,决定选用连续5级船闸方案.与分散3级船闸相比,该方案的主要优点是,船闸的布置紧凑,运行管理简单,线路长度短,线路位置与枢纽施工场地总布置的矛盾小,工程的施工强度低,枢纽的发电工期少1年,船闸的工程量和造价明显节省,船闸的主要工程技术问题通过较深入的研究已有较落实的解决措施。
The Three Gorges permanent navigation ship lock system which has the total water head of
113 metres high is a large-scale ship lock with the highest total water head of the world. After many
years of study on the schemes of the ship locks grading and location of lines, especially, study on five-
stage flight locks and three-stage seperate locks with two intermediate navigation channels, the five-
stage flight locks was chosen finally. Compared with the three-stage seperate locks, the main advan-
tages of the selected scheme are as follows: provide a compact ship lock arrangement, simplify the run-
ning management, provide a shorter tract length, decrease the contradiction between the line location and
the arrangement of the project construction, facilitate electricity generation one year earlier, decrease no-
tably the construction quantities and cost of the ship lock system. the solutions to the main technical prob-
lems of the ship lock have already been achieved through careful studies.
