THE CONSTRUCTION MONITORING TECHNIQUE OF CAST-IN-SITU CANTILEVER RIGID FRAME BRIDGE

The construction monitoring method of cast-in-situ cantilever rigid frame bridge is introduced，which includes structure analysis，data collection in field，parameter identification，model modifying and construction instruction. By data cellection in field，model modifying，command-giving，the designing status of the bridge is guaranteed. Taking the Dapo Guijiang bridge of Majiang-Wuzhou Expressway Project for example，it is introduced the monitoring method. The measured data show that excellent effect has been got by the monitoring method.
