摘要
该文结合某铁路特大桥40.7 m+60 m+40.7 m预应力混凝土连续箱梁施工过程控制实践,详细介绍了施工阶段各截面预拱度的设置、立模标高的计算以及控制截面的应变测试,确保了该桥的顺利合龙及施工安全,可为类似桥梁的施工过程监控提供参考。
According to the construction process control of 40.7 m+60 m+40.7 m pre-stressed concrete continuous box girder for an overlarge railway bridge,the article introduces in detail the setting of various section cambers,the calculation of template elevation and the strain test for controlling the sections in the construction stage,which ensures the smooth closure and the construction safety of this bridge,and can provide the reference for the construction process monitor and control of the similar bridges.
