In this paper, track irregularities, which are referred to as "track randomexcitation functions", are described in respect of their effects, interpretation,measurement, evaluation and control. This paper also deals with the characteri-stics of waveforms, power spectrum density and autocorrelation obtained fromactual measurement of track irregularities. The following points are mentioned: (1) Due attention must be given to, besides the amplitude, the effects of wavelength, ratc of change and resonantwaveform of the track irregularities; (2) The wavelengths to be measured forprofile irregularities in China at present should be from 0.1--30m; (3) Trackrandom excitation functions appearing to be highly irregular possess some sortof statistical characteristics and certain statistical patterns" (4) It is of impo-rtancc of using statistical functions such as the mean square value and PSDetc., to interpret the characteristics of track irregularities in respect of rese-arch on wheel/rail interactions and scientific evaluation the quality of trackmaintenance; (5) The measured data show that sample values of track randomexcitation functions are not necessarily stationary all the time; (6) Theaccuracy of the measured results relies greatly on the measurement techniquesadopted; (7) Graphical analysis and tests have further unveiled the defects byusing the "chord offset method", which has been used for a long time in Chinaand other countries, while the inertia technique, on the other hand, providesdata which conform closely to the actual waveforms. The author recommends that it is essential to improve and perfect the tech-niques for the evaluation and control of track irregularities by way of evalua-ting the smoothness of the track using "mean square value", or avariance", and"PSD" for determination of the sections of track to be enlisted in the periodicalmaintenance plan; of evaluating the regional characteristics of track irregul-arities by the three parameters of peak amplitude, mean rate of change andresonant waveforms for determination of the specific places requiring urgerltrepair or spot maintenance.

本文将轨道不平顺称为“轨道随机干扰函数”。论述轨道不平顺的种类、影响、描述、测量、评价与管理,以及部分测得的轨道不平顺波形、功率谱密度、自相关的特性。文中指出:不应只注意轨道不平顺的幅值,还必须重视波长、变化率、谐振波形等的影响;目前我国需测量考查的高低不平顺波长范围应为0.1米至30米;表面上杂乱无章的轨道随机干扰函数都具有某些统计特征和统计规律性;用均方值、功率谱密度等统计函数来描述轨道不平顺的特征,对轮轨相互作用和科学评价轨道养护状态的研究有重要意义;实测资料表明轨道随机干扰函数的样本记录并非都是平稳的;测量轨道不平顺的方法对测得结果的真实性有很大影响;图示分析和试验考查进一步揭示我国及许多国家长期使用的“弦测法”有严重缺陷,“惯性基准法”测得的结果与实际波形较为符合。作者建议改进评价、管理轨道不平顺的办法,用“均方值”或“标准差”、“功率谱密度”来评价轨道的平顺状态,确定应列入计划维修的里程段落;用峰值、平均变化率、谐振波形等三个参数来评价轨道不平顺的局部特征,确定需要局部维修或紧急补修的地点。
