Practice and analysis on continuous girder bridge construction monitoring

Due to the complicated bridge construction environment and management,in order to ensure the quality and safety,an increasing number of construction monitoring is introduced in the bridge construction,it seems the load-carrying capability and deformation of beam in critical stage can be in real-time monitoring and control,so bridge can be always in control.This paper,combined with a continuous bridge of cantilever construction,discussed the key issue encountered in the construction monitoring,which can provide a reference for similar construction monitoring.
