The Permit Management and Safety Assessment of Shengli Bridge under Overweight Vehicle

With the development of transportation industry, the number of times that overloaded vehicle pass through bridges increases day by day. Taking Shengli bridge as an example, the bridge model was established with finite element software in this paper. According to the vehicle parameters, the vehicle loading model was abstracted, and the process that overloaded vehicle pass through the bridge was simulated. Finally, the safety margin of the bridge was evaluated on the basis of bearing capacity analysis. Permit management measures for the bridge were proposed, which can be referenced by relevant situation.
