基于有限元理论的路面加铺层结构设计方法研究

我国沥青路面已逐渐进入大修补强期,因此研究合理的路面补强设计方法意义重大.采用有限元方法对路面加铺结构设计进行研究,结果表明:有限元方法能较好地模拟车辆荷载作用下的沥青加铺层内以及下卧层中的荷载响应.

Pavement Overlay Structure Design Method Based on Finite Element Method

Asphalt pavement has been gradually entering into a period of overhauling reinforcement in China, so to study the pavement strengthening and rational design methods is particularly significant. This paper studies the pavement overlay structure design method by using the finite element method. The results show that the finite element method can well simulate the load response in the asphalt overlay and the underlying layer under the action of vehicle load .
