Abstract
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 on the engineering practice, the control measures of the box girder creep camber were put forward, which can be taken as a reference and experience guidance for the similar projects.
