本文以张石高速公路石家庄北出口支线工程滹沱河特大桥为例,根据桥梁健康监测系统设计准则,考虑监测系统的投资额和系统的目的和功能,通过埋设在结构控制断面长期检测的应变计测量桥梁结构应变和应力,对桥梁健康状态进行安全监测。从而比较客观的对滹沱河特大桥的运营、管养提供理论依据,保障该桥正常健康运营。 Taking the Hutuo River Bridge as an example, according to the bridge health monitoring system design criteria, considering the investment amount of the monitoring system and the purpose and function of the system, this paper analyzes the long-term monitoring strain gage buried in the structural control section Measure the strain and stress of the bridge structure and conduct safety monitoring on the bridge health status. This will provide a theoretical basis for the operation and maintenance of the Hutuo River Super Bridge and ensure the normal and healthy operation of the bridge.
