摘要
为明确路面路基协同工作机理,指导实际工程中结构组合优化,以某高速公路3种路床搭配两种典型半刚性基层沥青路面建立了有限元模型,在总结分析沥青路面常见损坏基础上,以路表弯沉、基层底面弯拉应力、路基顶面竖向压应力为指标,研究了共6种结构组合的工作性能,对沥青路面与路基的结构设计具有一定指导意义。
In order to optimize structure combination at field from view of mechanism of interac- tions between pavement and subgrade, finite element models were established with summary of common distress of ac pavement, deflection.tensile stress at the bottom of base and vertical compress stress at the top of subgrade were chosen as evaluation criterion. Total six structure combinations performance were studied based on FEM results, thus guidance of ac pavement and subgrade were achieved.
