摘　　要：为了分析路面结构在轮胎移动载荷作用下的动力响应,采用Abaqus有限元软件建立轮胎-路面三维模型,研究沥青路面面层的竖向、横向、纵向的应力应变、剪应力、剪应变的变化规律。结果表明,路面载荷区竖向应力最大值出现在上面层,横向应力、纵向应力、剪应力的最大值出现在中面层。竖向应力最大,纵向应力和横向应力相当,剪应力最小。路面的竖向、横向、纵向应变最大值出现在中面层,剪应变最大值出现在中面层和下面层交界处。纵向方向的拉压应变反复作用,导致剪应变出现正负交替变化,加剧了路面疲劳破坏和车辙破坏。In order to analyze the dynamic response of the pavement structure under the action of the tire moving load,the Abaqus finite element software is used to establish the tire-pavement 3D model,study the vertical,horizontal and vertical stress strain,shear stress and strain changes of the asphalt pavement surface layer.The results show that the maximum value of vertical stress in the pavement load area appears in the upper layer,and the maximum value of transverse stress,longitudinal stress and shear stress appears in the middle surface layer.The vertical stress is the maximum,longitudinal stress is about the same size as transverse stress,and shear stress is minimal.The maximum strain of the vertical,transverse and longitudinal of the pavement appears in the middle layer,and the maximum shear strain appears at the junction of the middle surface layer and the lower layers.The repeated action of the tensile and compressive strains in the longitudinal direction leads to the alternating change of the positive and negative shear strain,which aggravates the pavement fatigue damage and rut damage.
