摘　　要：关于主梁有效宽度的分析研究方法和工程应用已有许多学者进行了较为广泛的研究,但其中都未谈及桥梁施工方法对主梁有效宽度的影响。本文以悬臂体系肋板式主梁斜拉桥为例,采用有限元仿真分析法,针对桥梁常用的整体现浇和悬臂浇筑两种施工方法对主梁有效宽度进行研究分析。Many scholars have been widely investigating the effective width of main girder and project application,however didn't refer to influence of construction method on effective width of main girder.Taking cable stayed bridge of cantilever system rib-slab main girder as example,the paper has carried out studies of effective width of main girder by finite element emulation,aiming at both construction methods of integral field cast and cantilever cast.Results indicate that the construction method will produce a relatively large effect on effective width distribution of main girder.
