摘要
通过有限元软件对某436 m跨径的宽桥面双塔双索面钢—混结合梁斜拉桥施工阶段的结构受力进行了分析,计算结果表明,在双悬臂施工阶段、单悬臂施工阶段以及安装桥面系阶段,桥梁的混凝土面板和钢主梁应力均满足规范要求,说明该桥施工阶段主梁安全可靠。
By finite element software,the thesis made a structure stress analysis in construction stage to one twin-tower and steel cable-stayed bridge with a 436 metre span-diameter bridge surface.The result of the calculation showed the tensions of the concrete plane and steel girder meet the standard requirements in double-cantilever construction stage,single-cantilever construction stage and the bridge-floor system installation stage,which indicated the girder of this bridge is safe and reliable.
