摘　　要：为了探究沥青路面结构层厚度对车辙变形的影响规律,利用ABAQUS有限元软件对不同结构层厚度情况下以及温度变化等外界因素进行综合模拟分析,根据正交试验原理,系统分析了不同结构层厚度情况下的车辙的变形结果,并对设计年限内的每公里造价对比分析,得出了最优的结构层厚度的组合(SMA-13采用60 mm、AC-20采用60 mm、AC-25采用80 mm、水泥稳定碎石300 mm),从而预防车辙的发生降低维修成本。Simulates the external factors such as different thickness of structural layer and the change of temperature with ABAQUS finite element software in order to explore the effect law of asphalt pavement structural layer thickness on rut deformation.According to the principle of orthogonal test,the deformation results of rut under different structural lay⁃er thickness are systematically analyzed,and the cost per kilometer in the design year is compared and analyzed,finally the optimal combination of structural layer thickness is obtained(SMA-13 adopts 60mm,AC-20 adopts 60mm,AC-25 adopts 80mm,and cement stabilized macadam 300mm),which will prevent the car from rutting and reduce the mainte⁃nance cost.
