摘要
采用ABAQUS有限元软件,建立了沥青路面有限元分析模型,分别从面层模量、面层厚度、温度、轴载等方面对沥青路面永久变形的影响因素进行了定量分析,结果表明:处理沥青路面车辙问题,不能仅从材料入手,应结合路面结构参数综合考虑。
Using finite element software ABAQUS,this paper established finite element model of asphalt pavement,respectively made quantitatively analysis on influence factors of asphalt pavement permanent deformation from surface layer modulus,surface layer thickness,temperature,axial load and other aspects,the results showed that,treatment of asphalt pavement rutting problems,not only from the material,but also should comprehensive considered combining with pavement structure parameters.
