| 摘 要： | 为了使车辙预估变得更为简便,提出一种基于应力松弛试验的改进的有限元车辙预估方法。研究结果表明：不仅从粘弹性力学的角度分析,应力松弛试验在理论上与Maxwell模型具有一致性,而且实例计算结果也验证了此方法的可行性。该方法便于不熟悉本构理论的工程人员进行车辙预估。

| Abstract: | In order to simplify the estimation of the deformation of asphalt layers,a modified method based on stress slack tests to estimate the deformation of asphalt layers is proposed.The result shows that not only the coherence between stress slack test and Maxwell model in theory is deduced by viscoelasticity analysis,but also its feasibility is proved by example.It is convenience for engineers who are not familiar with constitutive theory to estimate the deformation of asphalt layers. |
