提高三峡船闸通过能力的若干措施研究*

三峡水库蓄水通航以来，通过三峡坝区货运量持续增长，通过能力已趋于饱和，而且船舶大型化发展迅速，目前通过船舶大约一半吃水大于原设计标准。科学合理地挖掘船闸的富余水深，增加过闸船舶吃水、提高船闸的通过量是当前需要解决的重要问题。采取理论研究与实船测试验证的方法，对三峡船闸的运行方式和过闸船舶、船舶吃水控制标准计算方法、船舶过闸实船试验、过闸船舶吃水控制标准等进行了系统的研究，取得了多项创新成果。

Measures to improve Three Gorges' lock capacity

After the impoundment and navigation of the Three Gorges reservoir,the volume of freight traffic passing through the Three Gorges dam area continues to grow,and the ability is tending saturated.Moreover,the vessels are getting to a tendency of great size and large tonnage,and nearly 50% of the passing ships’ draught exceeds the designed standard.So it is an important matter to excavate under the kneel clearance to raise the passing ships’ draught and boost the volume of the passing ships are the today’s important problems.Combining the theoretical research with the on-board measurements,we carry out a systemic research on the running of the Three Gorges vessels,computing methods of the control standards about the volume and ship draught,on-board measurements of ships passing the lock and the control standards of the sea gauge,and have achieved several innovative achievements.
