摘　　要：为检验我国现有超重车辆认定标准的合理性,采用美国桥梁限载分析方法对中国的典型车辆模型进行校准。首先,以美国桥梁限载公式为基础,系统分析桥梁限载公式的基本形式及限载计算方法;其次,介绍中国现行超重车辆认定标准;最后,选取《公路桥梁汽车荷载标准研究》中典型车辆模型,采用美国桥梁限载公式对中国的典型车辆进行限载分析。结果表明:在对桥梁限载分析时应同时考虑车辆的轴载与轴距参数;我国超重车辆认定标准尚不规范,典型车辆的车货总重限值、双联轴载限值与三联轴载限值高于美国桥梁限载的界定标准;建议我国超限车辆认定标准采取考虑轴载与轴距参数的车辆荷载限值。To examine the rationality of the existing overweight vehicle standards in China, American bridge limit load analysis method is used for China＇s typical vehicle calibration. First of all, on the basis of American bridge limit load formula, the basic form of systematic analysis of the bridge limit load formula and using method of typical vehicle. Secondly, this paper introduces the current Chinese standard overweight vehicles. Finally, this paper selects the study of highway bridge vehicle load standard of six kinds of typical vehicle, using American bridge method for calculating the limit load formula of Chinas typical vehicle for calibration . Results show that the overweight vehicles standards has many shortcomings, such as： standard overweight vehicles in our country is not standard, and determined on the basis of not clear of overweight vehicles, defining the standard is not unified ; Typical vehicle axle load limits and car cargo gross weight limit is higher than by the bridge limit load calibration formula of axle load limits to cargo gross weight limit of the car. This paper suggest consider overrun vehicle standards adopted by the Chinese wheelbase parameters of vehicle load limit.
