摘要
该文以临近堤岸的某钢围堰大型临时结构施工为背景,基于有限元分析软件分析围堰的强度、刚度和稳定性.研究结果表明:随着壁板厚度的增大,各构件的最大应力值均呈现逐渐减小的趋势;将围檩由I40 替换成2I45 工字钢,可降低结构局部的位移、组合应力和剪切应力值;对围檩的构造和连接方式进行优化,可增加钢围堰的稳定性和抗倾覆能力.
Abstract
The present study is based on the construction of a steel cofferdam in proximity to an embankment.The objective is to calculate and analyze the strength,stiffness and stability of the steel cofferdam using finite element software.The results demonstrate that as the thickness of the wall plate increases,the maximum stress value of each member exhibits a gradual reduction.Furthermore,the utilization of I40 to 2I45 I-beam walings results in a reduction in the local displacement,combined stress and shear stress value of the structure.Additionally,the optimization of the walings'structure and connection method enhances the stability and overturning resistance of the steel cofferdam.
