Abstract
In order to meet the requirements of the industry for the high efficiency, safety, and reliability of the traffic safety assessment of heavy-duty vehicles, this paper proposed a method that combined a real-time monitoring system with a finite element method for the traffic safety assessment of heavy-duty vehicles on bridges and verified the method through practical projects. The paper evaluated the bridge’s technical condition level before the heavy-duty vehicle passes and determined the resistance reduction factor considering the bridge’s technical condition level. The finite element analysis model of the bridge was established, and the reliability of the model was verified by the measured data. On this basis, the safety assessment of the bridge was carried out by the actual load checking method. The bridge was also monitored in real time during the passage of heavy-duty vehicles. The results show that the technical condition level of the bridge is Class A. The finite element model of the real bridge can reliably evaluate the bearing capacity of the bridge. During the passage of heavy-duty vehicles, the bridge is in an elastic state, and the passage of heavy-duty vehicles does not cause damage to the bridge structure.
