Track Irregularity Power Spectrum and Numerical Simulation

  • Xiaoyan LeiEmail author


The railway track is an engineering structure whose operation and maintenance are undertaken at the same time. Due to long-time running, the accumulated deformation of track structure is increasing, which would cause various kinds of track irregularities: track profile irregularity, track cross-level irregularity, track alignment irregularity and track gauge irregularity.
