水中承台单壁钢围堰的设计及有限元分析

Analysis on the design and finite element of single-wall steel cofferdam of the bearing platform in water

以某特大桥为工程背景,详细介绍了单壁钢围堰的设计参数,同时对单壁钢围堰施工中两个最不利工况进行了有限元分析,结果证明结构的位移和应力均满足承载力要求,从而对类似施工具有指导作用。

Taking the ultra bridge as the engineering background, the paper introduces the design parameter of single-wall steel cofferdam, earries out finite element analysis on two unfavorable construction conditions in single-wall steel cofferdam construction. Results show that structural displacement and stress meet bearing capacity demands, which will be certain guiding sigrtifieanee for similar construction.
