摘　　要：大悬臂预应力盖梁是桥梁盖梁设计中一种常见结构,其施工工艺也较常规盖梁有所不同。传统盖梁施工多采用落地支架和抱箍托架,有一定局限性。通过江罗高速的大悬臂预应力盖梁施工,总结了一套高效经济的对穿钢棒安装贝雷托架施工方法,为同类型的盖梁施工提供了参考和借鉴。Large cantilever prestressed capping beam is a common structure in bridge capping beam design, and its construction technology is also different from conventional capping beams. Traditional capping beam construction mostly adopts floor-mounted bracket and hoop bracket, which has certain limitations. Through the construction of large cantilever prestressed capping beam of Jiangluo expressway, a set of efficient and economical construction methods for installing Bailey brackets on steel bars are summarized, which can provide reference for the construction of the same type of capping beam.
