Research On Method Of Ballastless Track Static Detection High-speed Rail

In recent years, the construction of high-speed rail speed and high-speed operation speed are greatly improved, the smoothness requirement of ballastless track on high-speed rail are increasingly high, high speed ballastless track static adjustment of ballastless track with high comfort foundation. This paper used high-speed rail static detection method based on the principle and process of high speed ballastless track static detection; track detection system in undisturbed conditions the maximum work area were calculated; and the gross errors in the detection data of static filtering denoising using wavelet analysis to remove the original. In the detection data of track static error; finally using curve interpolation theory to improve track static detection method:field data collection line using interval two sleeper detection curve section by interval a sleeper detection will detect the data collected after the three spline function interpolation detection the data of each sleeper, to reduce the workload and improve work efficiency objective.
