摘要
介绍了有限元方法的基本理论,着重分析ABAQUS方法中蠕变模型的原理,以及运用其分析沥青混合料特性的可行性。并进行蠕变试验得到沥青混合料的材料参数,在合理的假定和简化基础上应用有限元软件建立模拟沥青混合料车辙变形的模型,对不同结构在重复荷载下的变形进行数值模拟和分析。
The basic theory of finite element method was introduced. The emphasis was the creep model in ABAQUS and the possibility of using it analyzing asphalt mixture, the material parameters of asphalt mixture were gained from creep test. A model of pavement by finite element software, ABAQUS, was built to simulate the permanent deformation of asphalt pavement, based on reasonable supposition and predigestion. The numerical results were compared with the track test and indicated that the approach was reliable.
