摘　　要：文中以典型波形钢腹板连续梁桥悬臂施工为工程背景,分析介绍其结构设计情况,利用MIDAS Civil软件对其进行全桥整体分析,利用ANSYS软件对零号块建模并进行空间应力分析。结果表明:零号块局部存在较大拉应力,在今后设计和施工中应加以重视。计算分析结果可以为该类型桥梁的设计和施工提供参考。Taking the cantilever construction of a typical corrugated steel web continuous beam bridge as the engineering background,this paper analyzes and introduces its structural design,carries out the overall analysis of the whole bridge with Midas civil software,and uses ANSYS software to model the zero block and carry out spatial stress analysis.The results show that there is a large tensile stress in the zero block,which should be paid attention to in the future design and construction.The calculation and analysis results can provide reference for the design and construction of this type of bridge.
