以陕西府店路运煤超重车辆为调查对象,由车辆载重特点和轴型分布特征将其分为9种类型;分析了此9种车辆模型超载超限情况。利用线性回归方法,得出超载与超限的函数关系,分析了二者的区别与内在联系;对道路桥梁上的超重车辆荷载,提出限载管理措施。利用等代荷载方法,与公路-Ⅰ级荷载相比较,确定出9种车型的限载系数和限载标准,评价了限载后车辆荷载特性,得出了车辆限载后提倡使用多轮、多轴的车型来装运的结论,为未来道路桥梁超重荷载管理、交通运输与路政管理提供理论依据与支持。
Taking the coal overloading vehicles in Fudian Road, Shaanxi Province as the investigation object, the vehicle load characteristics and axial distribution characteristics are divided into nine types; the overload of these nine kinds of vehicle models is analyzed. Using the linear regression method, the functional relationship between overload and overrun is obtained, and the differences and internal relations between the two are analyzed. The limit load management measures are proposed for the overloaded vehicles on the road and bridge. By using the method of equivalent load, compared with the road load of class I, the load-carrying coefficient and the load-carrying standard of nine kinds of vehicles are determined, the load characteristics of the vehicle after the load is evaluated, Multi-axis model to the conclusion of the shipment for the future road and bridge overweight load management, transport and road management provide a theoretical basis and support.
