摘　　要：以某大桥主桥上部结构单箱双室预应力连续梁施工工程为依托,采用合理借助满堂支架作为箱梁浇筑外侧桁架模板,提高了满堂支架的整体稳定性和安全性,保证了箱梁的施工质量。施工中支垫梁槽钢与分配梁工字钢Ⅰ14焊接方式连接,通过此措施安全优质地完成了单箱双室预应力连续梁施工,为以后类似施工提供了技术借鉴。Based on the construction of single box and double chamber prestressed continuous box-girder,the full frame with reasonable design is used as the outer formwork of the box-girder,the whole stability and the safety of the full frame are improved,and the construction quality of the box beam is ensured. In the construction,channel steel of support beam and distributive girder are welded by I14 welding. Through this measure,the single box and double room prestressed continuous beam construction is finished safely and high,which provides the technical reference for the similar construction in the future.
