摘要
采用三维有限元方法,对重载交通条件下组合式基层沥青路面结构进行了模拟计算.对不同考核指标采用了正交试验,并进行了影响因素分析.研究结果表明,理想的组合式基层沥青路面结构应是具有较厚的、模量适中的基层材料,并且具有厚的、模量适中的稳定土底基层和强度较高的土基.
Based on three-dimensional finite element method,the simulation calculation for combined base asphalt pavement structure under heavy traffic was carried out.The orthogonal method for different factors was chosen and the results of influence factors were analyzed.The results show that the ideal pavement structure should have rather thick base materials with temperate module,rather thick stabilized soil subbase with temperate module and soil subgrade with high strength.
