摘要
为了研究沥青路面受到车辆荷载作用产生车辙破坏最严重的结构层,应用数值模拟建立了沥青路面的三维模型,运用瞬态动力学分析沥青路面各个结构层在动态荷载作用下产生的竖向变形量,从而得出受到荷载作用产生车辙破坏最严重的层位,为沥青路面的结构设计提供参考。结果表明:沥青路面产生车辙变形量最大的位置出现在荷载作用的中心线处;在动荷载作用下沥青路面的面层是产生竖向变形最大的结构层。
In order to research the distribution of asphalt pavement under the dynamic load,finite element model of pavement was built up by means of numerical simulation,and different layers of surface coursing＇s vertical displacement were analyzed by using transient dynamic.Concluded that the most serious destruction structure layer.Provide reference for the design of asphalt pavement structure.The results showed that： the surface coursing＇s vertical deformation was the largest under the load and destroyed mostly by analyzing surface data.The surface of the asphalt pavement was influenced by load was the largest structure layer.
