摘　　要：桥梁工程传统施工方案常用满堂支架工艺,进行混凝土箱梁现浇,近些年我国公路桥梁建设快速推进,满堂支架施工工艺,已无法满足不断提高的施工技术要求。钢管桩支架施工工艺具有施工速度快、施工成本低等优点。基于此,本文基于桥梁工程实例,探讨钢管桩支架施工工艺在现浇箱梁施工中的应用。The traditional construction scheme of bridge engineering commonly used full-hall bracket technology,concrete box girder cast-in-place, in recent years, with the rapid development of Highway Bridge Construction in China,the construction technology of full support can not meet the ever-increasing construction technical requirements. The construction technology of steel pipe pile support has the advantages of high construction speed and low construction cost.Based on this, this paper discusses the application of steel pipe pile bracket construction technology in cast-in-place box girder construction based on bridge engineering examples.
