中文摘要：

为研究移动荷载作用下级配碎石柔性基层沥青路面力学响应规律，利用ABAQUS有限元分析软件建立路面结构模型，探讨移动荷载作用下级配碎石柔性基层沥青路面竖向位移、各向应力和应变的力学响应．结果表明：级配碎石柔性基层对沥青面层竖向位移影响很大，路面结构内部应力应变变化情况复杂，设计过程中应控制各结构层最不利应力及应变满足设计要求．

英文摘要：

In order to obtain the dynamic response pattern of graded macadam flexible base asphalt pavement under Moving Load. Flexible base asphalt pavement model is established by ABAQUS finite element analysis software to study the dynamic response of the vertical displacement and stress-strain under moving load. The conclusion can be drawn that： the graded macadam flexible base has a remarkable effect on vertical displacement of asphalt pavement, Changes of stress and strain is complicated in pavement structure. The most adverse stress and strain should be satisfied the design requirements in the process of pavement design.
