Abstract:In order to meet the requirements of refined management of railway track, the paper described the in- vestigation on power spectrum density calculation and statistical processing for track irregularity inspection data of Wuhan - Guangzhou Passenger Special Line in 2013. The general spectrum structure of the upper - lower bound- aries and suggestion spectrum, were established by adopting a new four - parameter fitting formula. Besides, the track irregularity spatial series should be constructed with the requirement of vehicle - track （or vehicle - bridge） system dynamical simulation being taken
