摘　　要：钢吊箱围堰以其诸多优点在大型桥梁施工中得到了广泛应用。结合某长江大桥的施工,对钢吊箱围堰的施工工艺和技术进行了介绍。由于该桥钢吊箱围堰体量和承受的荷载均较大,并且结构复杂,为了研究受力特性,确保施工安全,进行了整体非线性仿真分析,得出的结论,可以为同类结构的设计和施工提供参考。The steel box cofferdam has been widely employed in the construction of long bridges for its advantages contrasted with other construction methods. Construction technique and method of suspended steel box cofferdam are introduced in conjunction with the construction of Anqing Highway Bridge over Yangtze River. Since its dimensions and loads imposed on it are large and the structure is complex, nonlinear simulation analysis of the monolithic structure by means of FEM has been made in order to study its mechanic features and ensure its construction safety. The conclusions drawn from this paper may serve as guidance and reference for the design and construction of similar structures.
