摘要
三峡工程二期围堰是在葛洲坝水库内兴建的，最大水深60m，堰体填料大部属于水下施工，是当今世界上最大的深水围堰，施工强度高、难度大、技术复杂，使其成为三峡工程建设中重大技术难题之一。主要阐述二期上下游横向围堰设计中的技术问题及其实施验证分析。
The second- phase cofferdam for the Three Gorges Project, built in the Gezhoubareservoir wtth a maximum water depth of 60 m, is so far the highest cofferdam in deep water in theworld, most of which was placed underwater. The construction of the cofferdam was one of the sig-nificant technical problems, arising from its high placement rate, numerous difficulties and sophis-ticated technologies. In this paper, the technical issues in the design of the second -phase transversecofferdam and analysis on operation of the cofferdam mainly are presented.
