Abstract Research purposes: It's difficult to effectively improve the amplitude of medium and long waves and control multi-wave irregularities with the existing track precision measurement and fine adjustment methods. Based on the current situation of railway precise adjustment in China and the variation characteristics of track irregularities, by analyzing the principle and improvement method of orbit detection, this paper studied on an improved operation method of track detection and fine adjustment based on the vertical deviation, in order to achieve the purpose of comprehensively improving the smoothness of railway works track fine adjustment.
Research conclusions: (1) The detection method based on the vertical deviation method can effectively reduce the amplitude of the long-wave irregularity in the track, and reasonably arrange the operation procedures, which can further improve short-wave amplitude and continuous track irregularities, and improve the track smoothness as a whole on the premise of orbit orientation/height optimization and improvement. (2) In the section of poor track condition and easing curve, the vertical deviation error measured by the inspecting instrument for railway track will be too large. (3) The customized adjustment of railway tracks based on the sensitive wavelength of the vehicle body can further improve the stability of the operation dynamic effect.

Key words： track irregularity precise measurement of railway tracks vertical deviation precise adjustment of railway tracks
