| 摘 要： | 汽车刹车引起沥青路面的破坏越来越多,沥青类路面损害越来越严重.采用ANSYS有限元分析软件,选取半刚性基层沥青混凝土路面典型结构建立沥青路面的三维有限元模型,对其进行数值分析.主要针对沥青混凝土路面特点,分析车轮制动行为作用路面的响应.分析结果表明,在车轮制动作用下半刚性路面的应力、垂直位移等大大增加,路面的疲劳破坏增大.同时,对沥青路面破坏提出了相关建议.

| Abstract: | More and more damages of asphalt concrete pavement are caused by braking of automobiles in recent years and trend to be more severe than that of before. The author creates a three-dimensional finite element model of a typical semi-rigid asphalt concrete pavement structure using ANSYS to do numerical analysis. The mechanical responses due to braking were analyzed based on the mechanical characteristics of asphalt concrete pavement. The results indicate that the stress, vertical displacements and fatigue failure due to braking all increase significantly. The author makes some suggestions to decrease the damages of asphalt concrete pavement due to braking. |
