Monitoring and control technology in cantilever construction of continuous beam bridge

The construction monitoring and control of a bridge is to monitor the structure stress, deformation and stability of a bridge in the construction process, and make the state of the structure optimal, ensure the bridge construction smooth and the final bridge in accordance with the design and specification requirements. Based on the supervision control of the cantilever construction of the continuous beam, this paper introduces the computation model of the continuous girder established by MIDAS/Civil; stress monitoring instrument selection, monitoring process and data processing; the elevation monitor for the top surface of the ridge and how to set pre-camber.
