摘要
考虑荷载作用下,沥青路面面层之间以及面层与基层之间,实际上可能处于接触状态。本文采用有限元技术对路面的接触非线性特性进行分析,结合高速公路的现场试验,比较表明,接触模型比层状体系模型更适合描述路面的力学特性。
The action between layers of asphalt concrete surface and aggregate base under load may be a contact problem in fact.By use of finite element method to analyze the road surface contact problem,this paper discusses the effectiveness of the method based on the comparison between the analysis results and the in-situ experiment outcomes.
