摘　　要：三峡工程大江截流的规模巨大，综合指标居世界同类工程的前列。在水深、流量大、工期紧的困难条件下，确保大江胜利截流，必须做好截流技术研究和相应的实施准备。宜昌科研所运用几个不同比尺及功能的水力学模型研究大江深水截流有关的水力学问题，提出大江截流平抛垫底，两岸戗堤提前进占的方案，可以顺利实现截流。it is essential for the river closure work of the Three Gorges Project with suchcomprehensive indexes as deep water, large discharge, large dumping quantity within a short timeframe without precedent for the similar works in the world, that researches on the technique ofriver closure and construction preparation should be fully conducted. The river closure can besuccessfully completed by lifting the elevation of the river bed, reducing the water depth byfrontal dumping from boats in advance, and advancing by end --dumping method from eitherbank in advance, based on several scales of hydraulic model experiments done by the YichangScientific Research institute.
