摘要

某大桥桥塔桩基采用双壁钢围堰施工。为准确了解钢围堰在施工过程中的应力和变形情况,采用大型通用有限元分析软件Midas/Civil进行详细分析。分析各工况可以看出,围堰在施工过程中各构件的最大应力均小于限值,结构稳定性满足要求。并且通过计算,围堰的抗浮稳定性也满足要求。该文分析结果可为同类工程施工提供参考。
        Double-wall steel cofferdam is used for the construction of the pile foundation of a double-wall steel cofferdam bridge. In order to correctly understand the deformation and stress of steel cofferdam structure during the construction process, this steel cofferdam is analyzed in detail with the finite element analysis software Midas/Civil. It can be seen from the analysis of each working condition that the maximum stress of each component of the cofferdam during construction is less than the limit, and the structural stability meets the requirements. And through calculation, the anti-floating stability of the cofferdam also satisfies the requirements. The analysis results can provide a useful reference for the construction of such projects.
