为了更加形象地模拟车轮与路面的实际作用情况,文中采用有限元数值分析方法,建立了路面在非均布力作用下的有限元模型.通过对荷载作用下沥青路面在不同材料参数、边界条件下的最大剪应力分析,得到了不同情况下沥青路面的最不利受力位置,从而为沥青路面车辙产生的机理分析提供参考,为路面结构和材料设计提供理论依据.

In order to simulate non-uniform load of the vehicle tires in fact, the finite element model under nonuniform load with finite element numerical analysis method is established. Through analyzing the maximum shear stress with the different material parameter and different boundary condition of the pavement structure, the most disadvantageous position of the pavement is found under the different condition, which provides references for analyzing the mechanism of rutting and provides the theory support for the pavement structure design and the material design.
