摘要
采用现场实测的方法对武广客运专线工程32 m预应力混凝土箱梁应力效果进行监测,并采用Mi-das/Civil结构分析程序进行了弹性上拱的理论分析,提出箱梁徐变上拱的控制措施,为同类工程提供借鉴及经验。
As a case for study, the online montoring and numerical analysis for 32 m concrete prestressed box girder prestressing and elastic camber effect in Wuhan-Guangzhou passenger express line was performed in the paper. The effect of monitoring and analysis, based girder creep camber were put forward, which can be projects. on the engineering practice, the control measures of the box taken as a reference and experience guidance for the similar
