摘　　要：为了保证钢结构建设质量,文章以桑茶快速路第一标段的A匝道桥梁为例,从总体布置、构造方案、防腐设计等方面着手,阐述了上部结构设计要点,并利用Midas Civil软件,对上部结构的正应力和稳定性进行验算,随后提出了一种新型钢箱梁翼缘板支撑体系,解决了传统脚手架施工钢箱梁存在的问题,研究成果可为类似钢箱梁项目提供参考和借鉴。In order to ensure the quality of steel structure construction,this paper takes the A ramp bridge in the first bidding section of Sangcha Expressway as an example to expound the key points of superstructure design from the aspects of overall layout,structural scheme and anticorrosion design,and uses Midas Civil software to check the normal stress and stability of the superstructure,and then proposes a new type of steel box girder flange slab support system,which solves the problem of steel box girders existing in the traditional scaffold construction.The research results can provide reference for similar steel box girder projects.
