摘　　要：浅析了三峡工程大江截流堤头坍塌机理，并研究了用小粒径材料截流、平抛垫底以减小水深的两种解决措施。研究结果认为：采用先平抛垫底到高程４０ｍ或４５ｍ，再立堵截流的方案比较现实可行。The slumping mechanism of the TGPs main channel closure dike is analysed in the paper. Two measures either using closure materials of small grain sizes or filling up the gaps bottom for reducing water depth are studied. The test results show that when the gaps bottom is horizontally rised up to an elevation of 40m or 45m at first, the closure can be easily completed by end dumping method. This scheme is feasible and will be practised for the TGP.
