随着交通运输业的发展,超重车过桥的情况日益增多。以河源市胜利大桥为例,以有限元分析手段建立桥梁分析模型,根据超重车参数抽象出车辆荷载模型,对超重车过桥的过程进行模拟计算。在对承载力分析的基础上研究了全桥的安全程度,给出了超重车过桥的决策建议及相关保障措施。研究成果可为类似情况提供参考和帮助。
With the development of the transportation industry, the situation of crossing the bridge of overweight trucks is increasing day by day. Taking Heyuan City Victory Bridge as an example, a bridge analysis model is established by means of finite element analysis, and the vehicle load model is abstracted according to the parameters of the overweight vehicle to simulate the process of crossing the overloaded vehicle. Based on the analysis of bearing capacity, the safety of full bridge is studied, and the decision suggestion and related guarantee measures for overpassing overweight truck are given. The research results can provide reference and help for similar situations.
