摘　　要：某大桥主桥采用双壁钢围堰的结构型式。为了准确了解钢围堰结构的变形和应力情况,确保工程施工安全,对该钢围堰用ANSYS软件进行了计算分析。控制性工况分析结果显示,围堰结构最大变形值较为合适,所有构件应力均低于设计条件既定的限值,结构稳定性能够满足规范要求。The structural type of double-wall steel cofferdam is used for the main bridge of a bridge.In order to correctly understand the deformation and stress of steel cofferdam structure and to ensure the engineering construction security,this steel cofferdam is calculated and analyzed by ANSYS software.The control performance analysis results show that the maximum deformation value of cofferdam structure is more suitable,all member stresses are lower than the limited values stipulated in the design stipulations,and the structural stability can satisfy the requirements of criterion.
