摘　　要：大直径钢圆筒作为码头、防波堤、护岸结构等曾在诸多工程中得到应用,但在海洋工程中作为钢围堰尚属首次,港珠澳大桥CB03标段桥墩工程施工以大直径钢圆筒作为钢围堰。文章采用有限元建模方式对钢圆筒围堰结构进行变形及应力分析,计算得到在水压力、水流力及土压力作用下钢圆筒筒壁及支撑结构的变形及应力情况。Large diameter steel caisson was used in many project, including wharf, breakwater and revetment structure, but it was the first time used as steel cofferdam in the Hongkong- Zhuhai- Macao Bridge CB03 section project which was oceanographic engineering. Finite element method was used in this paper to analyze the deformation and stress of large diameter steel caisson. The deformation and stress of the steel caisson wall and support structure under the load of water pressure, soil pressure and the flow stress are calculated.
