摘　　要：交通负荷是通过各种方法进行路面设计的主要输入量。路面最终结构配置的选择受到许多因素的影响,这些因素以代表性值或平均值进入设计过程,这意味着其属性的内在可变性,从而影响设计的可靠性和路面的耐久性,设计过程应考虑控制路面性能的因素的变化性和不确定性。文章利用车辆重量数据库,通过模型计算不同荷载条件、不同沥青厚度条件下车辆对路面刚度及沉降值的影响,以此调查超载车辆对公路路面使用的影响情况。研究表明,与具有合法负荷的相同车辆相比,超载车辆会明显影响公路路面的耐久性。Traffic loads are the main input to pavement design through various methods.The selection of final pavement structure configuration is affected by many factors.These factors enter the design process with representative values or average values,which means the inherent variability of their properties,thereby affecting the reliability of the design and the durability of the pavement.The design process should take into account the variability and uncertainty of the factors that control the performance of the pavement.In this paper,the vehicle weight database is used to calculate the influence of vehicles on pavement stiffness and settlement under different load conditions and different asphalt thicknesses through the model,so as to investigate the influence of overloaded vehicles on the use of highway pavement.Research shows that the overloaded vehicle will significantly affect the durability of highway pavement compared with the same vehicle with legal load.
