摘　　要：以有限元软件ANSYS为计算工具,应用弹性和弹塑性理论,对重载沥青路面结构进行数值分析,研究了路面结构在双轮车辆荷载作用下的力学响应,提出了路面设计指标增加沥青层层底拉应变和路基顶面压应变控制指标。Numerical simulation analysis about heavy-loaded asphalt pavement was performed using elastic and elastic-plastic theories with finite element analysis software ANSYS,and the mechanical responses of pavement in two cyclic traffic loads were studied.Proposing that increases the pavement design target such as tensile strain of asphalt bottom layer and road bed pressure strain.
