Abstract: The Yangtze River has always been called as the "Golden water way", so full attention should be paid to the planning, design, constraction and operation management of the shiplocks of the Three Gorges Project in order to make the water transport in this river well-operated. In this article, three types of shiplock models, "successive five-stage shiplock", "three-stage shiplock with a channel in the middle" and "three-stage shiplock with a regulating, water pool", are analysed and compared from the point of view of technology, economy and operation management. And the three-stage shiplock with a regulating water pool is considered to be the more ideal shiplock model for the Three Gorges Project.

Key words: Three Gorges Protect, shiplock model, five-stage shiplock, thtee-stage shiplock

摘要： 长江素称中国的"黄金水道",确保长江水运畅通是三峡水利枢纽船闸规划、设计、施工及运行管理都必须高度重视的问题。本文从技术、经济及运行管理的角度对"连续五级船闸"、"具有中间渠道的三级船闸"及"带调节水池的三级船闸"等3种船闸型式进行了分析、比较,最后认为"带调节水池的三级船闸"是三峡水利枢纽较理想的船闸型式。
