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.
