Abstract:The track irregularity power spectrum density （PSD） of railway was obtained based on mass of track irregularity data in recent years, and the qualitative and quantitative investigations on the judgment method of track irregularity were made. Based on the thread of establishing the general track PSD according to the railway speed grade of main railway lines in China, the qualitative judgment methods for track irregularity of the speed-increase lines with the speed of 200 and 160 km · h^-1, as well as general line with the speed of 120 km · h^-1 , are investigated and put forward, in which the t
