| 摘 要： | 分析了康托尔三分集，介绍了分形与分形维数的基本概念，运用频谱分析的方法对路面不平度曲线的分形维数进行了计算。结果表明，路面不平度的分形维数越低，所含低频成分能量越高，道路越平坦。结合路面不平度系数，可以对路面不平度的复杂程度作出判断。

| Abstract: | The fundamental concept of fractals and the fractal dimension are explained by Cantor aggregate.The fractal dimension of road roughness is computed by means of the frequency-spectrum method.The results shows that the more flat the road surfaces are,the smaller the values of fractal dimension are.Fractal dimension combined with road roughness coefficient can be used to evaluate roughness of road surface. |
