摘要
悬臂现浇连续刚构桥的施工监控方法,主要包括结构计算、现场数据采集、参数识别、修正模型、指导施工等几个要素。监控具体通过现场数据采集、修正模型,得到有用数据、下达施工指令来保证实现桥梁成桥后的设计状态。结合马梧高速公路大坡桂江大桥工程实例,简要给出了桂江大桥的监控示例。实测数据表明,大桥监控取得了良好效果。
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.
