| 摘 要： | 为了揭示刹车反复作用下沥青路面剪切动响应力学行为特征,应用ABAQUS建立了典型半刚性基层沥青路面三维计算模型,针对沥青路面剪切动响应控制性外部影响因素,以及单次及反复刹车作用下沥青路面剪应力与水平位移变化规律进行了数值模拟分析.计算结果表明:加速度和阻尼比对路面结构残余水平位移存在较大影响;刹车作用效应随着深度的增加而迅速衰减,路表呈现为波浪形的剪切推移变形特征;反复刹车导致沥青路表残余变形缓慢累积.作用次数达到106次后可形成波浪形车辙病害.

| Abstract: | In order to investigate the shear dynamic response of asphalt pavement under repeated brake load,a three-dimensional numerical model for the semi-rigid base asphalt pavement was presented by using ABAQUS.Some numerical simulations were conducted for the dominant external influence factors on the shear dynamic response,shear stress and horizontal displacement variations of asphalt pavement under one-cycle and repeated brake loads.The calculation result shows that(1) the influences of the acceleration and dam... |
