摘　　要：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 transportation industry,the number of overloaded vehicles passing through bridges increases day by day.Taking Shengli Bridge for example,the bridge model was established with finite element software.According to the vehicle parameters,the vehicle loading model was abstracted,and the process that overloaded vehicle passing through the bridge was simulated.Finally,the safety degree of the bridge was researched on the basis of bearing capacity analysis,and suggestions and measures for the bridge were proposed,which can be referenced by relevent people.
