| 摘 要： | 利用有限元软件建立多个不同的倒装式路面结构模型进行计算，并将计算结果导入到nSoft软件进行疲劳分析，得到不同倒装式路面结构模型的抗疲劳性能。根据灰色关联分析理论，对得到的不同倒装式路面结构的抗疲劳性能进行灰关联分析，得出各倒装式路面结构参数对倒装式路面结构抗疲劳性能影响程度的依次顺序。研究结论对以提高倒装式路面结构抗疲劳性能为目标的路面结构调整有一定的指导作用。

| Abstract: | Finite element software is used to establish many different inverted pavement structural models to perform calculation and lead the calculation results into nSoft to perform fatigue analysis. Therefore, anti -fatigue properties of different inverted pavement structural models are obtained. According to grey relational analysis theory, the analysis is performed on the anti - fatigue properties of different models and proper sequence of the influence degree of various inverted pavement structural parameters on anti - fatigue property is gained. The research conclusion has certain instruction function to the adjustment of the inverted pavement structure into targeted pavement structure through improving anti -fatigue property. |
