| 摘 要： | 在桥梁基础建设中，钢吊箱围堰作为一种临时阻水结构，广泛应用于大型深水基础的施工中。钢吊箱的施工质量直接关系到桥梁基础乃至整座桥梁施工的成败与否。本文采用通用有限元程序ANSYS对国内某特大跨桥梁6号钢吊箱结构的施工工况进行数值模拟，基于工程中常用的计算方法和线性绕射理论法分别对钢吊箱各个工况进行了静力分析，并讨论了不同波浪作用方式下钢吊箱的力学性能。

| Abstract: | As a temporary water retaining structure in the construction of bridge foundation, steel suspended cofferdam is widely used in the construction of large deepwater foundation. The quality of construction of steel suspended cofferdam decides whether the bridge foundation, even the whole bridge, can be successfully built. In this paper, static finite element analysis of No. 6 steel suspended cofferdam of one super large - span bridge in China was carried out in two ways. The first one was usually applied in project, while the other one considered the diffraction effect of wave force. Finally, the mechanical properties of steel suspended cofferdam under different modes of wave action was studied. |
