论文以实体工程为依托,在试验研究基础上,运用ABAQUS软件分别对三种不同基层材料组成的路面结构建立模型,分析其力学响应特性。结果表明沥青面层处于受压状态,基层底面处于受拉状态,土基顶面处于受压状态;三种基层路面结构纵向拉应力均大于横向拉应力,且乳化沥青冷再生层的路面顶面弯沉值和拉应力最大,能较大程度地将荷载及应力分散,表现出明显的柔性基层的特性,具有很好的抗疲劳性能,对于防治反射裂缝贡献较大。

〔Abstract〕 Mechanical response characteristics were analyzed in this paper and three pavement structure modes of materials were built in ABAQUS software based on real engineering and experimental study. Re-sults showed that the asphalt layer bottom is in a state of tension at the grass-roots level, the top of the soil base in the compression state as the surface layer in compression. Three primary longitudinal tensile stresses in pavement structure were greater than the transverse tensile stress, and pavement deflection value along with tensile stress were great at the top of the emulsified asphalt cold regeneration layer. It can greatly spread load and stress, showing good characteristics of flexible base and fatigue resistance performance. All above can contribute to the prevention and reflection crack.
