摘　　要：为探索高速公路桥梁车辆荷载模型的建立方法,选取了沈海高速(G15)福宁段下白石特大桥,基于动态称重(WIM)系统监测信息,在统计分析通行车辆连续到达车间距、车重等信息的基础上,对下白石大桥车辆荷载效应进行了分析,基于分析结果建立了下白石大桥车辆荷载模型,并将该模型应用于真实桥梁的车辆荷载效应评估。研究表明:基于平衡更新过程和荷载等效的车辆荷载理论具有一定的合理性,所建立的车辆荷载模型能够用于既有桥梁的承载能力分析。We selected Xiabaishi Bridge on Funing section, Shen-hai Expressway（ G15 ） to study the establishment of the expressway bridge vehicle load model, based on the monitoring information of weight-in-motion （WIM） system, and analyzed the effect of the bridge vehicle load based on the statistic of continuously arriving vehicle spacing and the vehicle weight, building the bridge vehicle load model, used to evaluate the real bridge vehicle load effect. The research shows that the theory of vehicle load is reasonable,and the model can be used to analyze the load-carrying capacity of the current bridges.
