摘要
在室内对路面各层和路基材料进行试验,以获得力学计算参数;考虑公路超载情况,利用有限元软件,对高速公路路面结构进行建模计算;并进行分析影响路面结构应力大小和分布的因素(主要包括路基刚度、层间连结状态),为高速公路路面结构设计和施工应用提供理论依据和指导经验。
This article carries on the test of the roadbed material in the room, and obtains mechanics computation parameter; Considered the road overload situation, we carry on the modeling computation to the highway pavement structure by using finite element software; Through analysis the factors which influence pavement structure stress size and the distribution （mainly includes roadbed rigidity, level linked condition） , this article provides the theory basis and the instruction experience for the highway pavement structure design and the construction application.
