| 摘 要： | 将路面不平度作为激励输入给交通车辆,引入功率谱密度函数PSD,采用数值分析方法,模拟了随机不平度激励下重载交通车辆随机荷载的产生机理。根据模拟结果阐明了路面结构的损伤破坏与路面表面特性及车辆载重、车速之间的依附关系,为公路动态随机交通荷载图谱的建立及路基路面结构的设计提供了依据和参考。

| Abstract: | The author simulates an experiment to observe the mechanism of heavy-loaded transportation vehicles,given the surface roughness and Power Spectral Density(PSD).The final result obtained from numerical analysis demonstrates that the damage of road structure,characteristics of road surface,carrying capacity of vehicles and speed of vehicles are linked with each other.The author hopes that this outcome can provide reference for the establishment of road dynamic random traffic load map and the design of road structure. |
