| 摘 要： | 沥青路面结构在外界环境作用下是气、液、固三相介质体,水和荷载的耦合作用导致了沥青路面初期损坏的产生,探究其在车辆移动荷栽作用下的动力响应是获知沥青路面结构行为的前提.首先,在沥青路面饱和情况下,作一级合理近似,将其视为流固两相介质.基于多孔介质理论,对于典型半刚性基层沥青路面结构建立了移动荷载作用下的三维有限元模型;而...

| Abstract: | Asphalt pavement is a kind of porous medium which consists of solid,liquid and gas phases under the action of outside environment.The coupled hydro-mechanical action leads to the initial failure of asphalt pavement.To explore the dynamic response of asphalt pavement subjected to moving vehicle loads is the premise for understanding the structure behavior of asphalt pavement.First,regarding asphalt mixture as a media consists of solid and liquid phases in level one reasonable approximation,based on the porou... |
