摘　　要：以河北省首座上承式拱形变高钢桁组合连续梁的设计与施工方案为例,通过方案比选,确定适合砖楼特大桥主桥上部结构的施工方案,详细论证了专项施工方案的各个环节,有效保障了高墩桥梁施工的安全和项目的工期要求,可供类似跨越工程参考和借鉴。Taking the design and construction scheme of the first deck-type arch composite continuous beam bridge with variable cross-section steel truss in Hebei province as the example,the construction scheme that is suitable for the superstructure of the main bridge of Zhuanlou super large bridge is determined through the scheme comparison and selection.All links of the special construction scheme are demonstrated in detail,which can effectively ensure the safety of the construction of high-pier bridges and the requirements of the project duration,and provide reference for similar crossing projects.
