大跨度连续刚构桥的施工监控

Construction Monitoring and Control of Long-span Continuous Rigid Frame Bridge

结合东江南特大桥工程实例,介绍了预应力混凝土连续刚构桥施工监控的目的、工况、仿真分析、线形和应力的控制、参数识别等。实测数据表明,大桥监控取得了良好效果。

Taking the Dongjiangnan super span bridge for example,the purpose,load condition,simulation analysis,the alignment and stress control,parameter identification of construction monitoring and control for prestreesed concrete continuous rigid frame bridge are introduced.The measured data show that excellent effect are got by the monitoring method.
