摘　　要：介绍了道路路面数据的测量方法和设备,讨论了测量数据中奇异信号的产生原因。在分析比较常用异常数据处理方法基础上,提出了适合于道路路面测量数据的奇异信号识别和自适应修正方法,并对此方法处理过程进行了详细介绍。最后,使用对实际采集路面数据中异常信号进行识别、修正的例子,充分说明了该方法的处理效果。实例分析结果表明,使用该奇异信号识别修正方法来处理异常数据,使用简单方便,修正效果良好,可在道路路面数据处理及其他实际工程振动信号处理中推广应用。Measurement methods and instrument of road surface profile are introduced,and causes of singular signal in measurement data are discussed.Based on analyzing and comparison of common singular data processing method, a singular signal identification and adaptive correction method for road surface profile measurement data is proposed,and the processing of this method is described in detail.Finally,using examples that singular signals in the actual road surface collecting data are identified and corrected,which fully illustrate the effect of this method.The example analysis results show that this method of singular signal identification and correction is simple and has obvious effect,so can be widely applied to road surface data processing and other practical engineering vibration signal processing.
