摘要:
为了研究沥青路面温度对路面弯沉的影响,考虑道路材料参数的温度敏感性,建立沥青路面有限元耦合模型.基于所建数值模型,分析了FWD动态加载作用下路面弯沉在不同温度条件下的变化情况,以及不同厚度沥青路面最大弯沉受温度的影响.同时分析了沥青路面结构及材料参数对动态弯沉温度修正系数的影响,最后基于耦合模型对沥青路面动态弯沉温度修正系数进行了研究,并与试验结果进行了对比.研究表明,路面厚度及基层模量对温度修正系数影响较大,基于有限元模型建立的沥青路面弯沉的温度修正系数与通过试验研究建立的温度修正系数吻合程度较高,可以作为试验研究的有效补充．
Abstract:
In order to study the influence of asphalt pavement temperature on pavement deflection, a finite element coupling model of asphalt pavement was established considering the temperature sensitivity of road material parameters.Based on the numerical model, the variation of pavement deflection under FWD dynamic loading under different temperature conditions and the influence of temperature on the maximum deflection of asphalt pavement with different thickness are analyzed.At the same time, the influence of asphalt pavement structure and material parameters on the dynamic bending temperature correction coefficient is analyzed. Finally, the dynamic bending temperature correction coefficient of asphalt pavement is studied based on the coupling model and compared with the test results.The results show that the pavement thickness and base modulus have great influence on the temperature correction coefficient. The temperature correction coefficient of asphalt pavement deflection established based on the finite element model is in good agreement with the temperature correction coefficient established through the experimental research, and can be used as an effective supplement to the experimental research.
