摘要
以郑西客运专线渭河特大桥为例,通过对26孔、44m节段拼装箱梁在施工阶段梁体挠度和变形观测数据的统计、整理、分析,详细介绍大吨位箱梁在荷载作用下挠度的监控工艺与方法,可为同类桥梁施工过程的挠度控制提供依据。
Taking Zhengzhou-Xi＇an Passenger Dedicated Line Weihe River Huge Bridge as an example,by counting,collating and analyzing the observation data of the beam deflection and deformation of 26 holes 44m segmental box girder in the construction phase,the monitoring technology and methods of the deflection of large tonnage box beam under load are introduced,which can provide basis for the deflection control of similar bridge in construction.
