摘要
强度理论是材料和结构设计的依据和准则,它的发展会对材料和结构的分析及设计产生新的思路和方法。我们试图对不同强度理论进行概述,简要总结不同强度理论的方法和步骤,着重于不同强度理论在沥青路面结构中的应用情况,并指出不同强度理论缺陷及其发展历程。就沥青路面结构层状结构的特点,提出沥青路面结构界面(层)研究的思路。
Strength theories are the guide lines in the design of material and structure, the development of them can bring some new thoughts and methods to the analysis and design of material and structure. In the basis of these, we try to summarize different strength theories, and sum up their methods and processes briefly, and importantly sum up their applications in asphalt pavement structure, and point out their limitation and development. According to the characteristics of layers in asphalt pavement structure, we put forward the research idea of inter-layers in asphalt pavement structure.
