摘　　要：针对沥青路面参数具有变异性的特点,采用蒙特卡罗法和沥青路面力学模型生成路面参数,并采用概率统计方法进行路面力学反应的变异性分析.根据此思路,以Matlab为平台,设计出沥青路面参数变异性分析的计算程序,并将该程序应用于沥青路面力学响应的变异性模拟分析.结果表明,模拟分析得到的沥青路面力学响应的分布与实际情况接近.文中还运用路面疲劳损伤模型考察了沥青路面结构参数变异对沥青路面疲劳性能的影响.According to the inherent variability of asphalt pavement parameters, some pavement parameters are generated by using the Monte Carlo method and the pavement mechanical model, and the variability of pavement mechanical responses is analyzed via the probability statistic method. A computer program is then developed on the Matlab platform to analyze the variability of pavement parameters and to further simulate the variability of mechanical responses. The results show that the simulated distribution of mechanical responses accords well with the practical one. The effects of variability of mechanical responses on the fatigue damage of asphalt pavement are finally discussed based on the fatigue damage model.
