关于三峡水利枢纽工程永久船闸设计方案的探讨

Discussion on the design proposals for permanent lock of the Three Gorges Proiect

用非等分水头运行原理，通过对多余水垫产生、扩散的阐述，揭示消除水垫的措施及其意义，并研究了具体的设计方案，以实现“既不影响船闸航运能力及其他功能，又能提高船闸安全运行的可靠性；既降低闸室边墙、闸门高度，减小闸门，降低技术难度要求，又能方便运行管理；既减少工程量及投资，又能实现节水发电”的目标的工程措施。

This paper describes the creation and diffusion processes of surplus water cushion and reveals the measures for eliminating water cushion and the significance based on the operation principles of non--uniform water head. And the practical engineering measures have been studied for achieving the following goals:it could not influence the navigation capability and other functions of lock but could increase the safe navigation reliability; it not only lower the chamber wall and the gate height and reduce the technical requirements and difficulties, but also will be easy for operation and management; it not only could reduce the porject quantities and investment, but also could reach the goal of water-saving and power generation.
