摘　　要：文中以济南凤凰路黄河大桥跨大堤引桥钢箱梁施工为背景,介绍了跨黄河大堤钢箱梁节段拼装支架的结构布置,提出了支架设计原则,并对支架进行建模计算,得到支架的受力和变形情况,同时以钢桁架代替繁重的型钢梁系结构,对支架进行优化,为项目部创本增效,为后续跨黄河大堤钢箱梁节段拼装施工支架设计提供技术参考。Phoenix road in jinan Yellow River bridge across the levee approach span steel box girder construction as the background,this paper introduces the Yellow River levee structure arrangement of the steel box girder segment assembling stents put forward the principle of design,and support for modeling calculation,get the support force and deformation,and replace the heavy type steel beam with steel truss structure,optimize the bracket,for the project department and the efficiency.This paper can provide a technical reference for the subsequent design of steel box girder segmentations for erection construction across the Yellow River embankment.
