Research on Setting Safety Warning Thresholds for Bridge Health Monitoring Systems
With the rapid development of the national economy,China's infrastructure has also been vigorously developed,and many highway bridges have also experienced serious degradation over time,leading to an increase in safety hazards of bridges.In order to ensure the stable development of highway engineering and the safety and stability of bridge structures,it is particularly important to establish a scientific health and safety monitoring system during the operation period.In the bridge health monitoring system,the bridge safety warning system is one of the core components,and the setting of safety warning thresholds is also crucial.This paper took the bridge health monitoring system of a certain expressway in Chongqing as the background,systematic research was conducted on security warning threshold setting.Two methods were proposed for setting warning thresholds:model free warning threshold method and the model based warning threshold method.And it was found that in the early stage of setting warning thresholds,the model based warning threshold method can be used for setting,and the model free warning threshold method can be used for setting when having a certain scale of database.
