| 摘 要： | 利用激光武不平度测试仪沿着行驶方向测定混凝土、砖、土路面的不平度,对每一种路面不平度的轮廓均方根偏差、轮廓微观不平度的平均间距、功率谱函数和分形维数进行了分析,结果表明:传统的粗糙度评定参数在描述各种路面不平度时具有明显的局限性,而利用分形维数可以较好的表征随机路面的不规则程度.

| Abstract: | By using of a laser profiler,the surface height variation trace of three types of road profiles,that is concrete,brick,soil,were obtained.Using these data the range of 、power spectral density function and fractal dimension were estimated.The results show that road surface is boundedness with the traditional estimated parameters,but the complex process related to the different road can be well described by fractal dimension. |
