文章介绍了Burgers模型的特点,选用Burgers模型模拟沥青混合料,使用prony级数展开Burgers模型的蠕变方程,得到修正的Burgers模型的蠕变参数,利用有限元软件ANSYS建立了路面结构的精细数值模型,分析结构在车辆循环作用下的力学响应,得到结构的抗车辙能力,为结构抗车辙分析提供了参考。
In this paper, the characteristics of Burgers model are introduced. Burgers model is used to simulate the asphalt mixture. The creep equation of Burgers model is developed by prony series. The creep parameters of the modified Burgers model are obtained. The fine numerical value of the pavement structure is established by finite element software ANSYS Model, the mechanical response of the structure under the action of vehicle cycle is analyzed, and the anti-rutting ability of the structure is obtained, which provides a reference for the structure’s anti-rut analysis.
