Popis:	To solve the problem that there is vertical track profile irregularity with long wavelength and large amplitude a method of adjustment based on cubic spline interpolation was proposed in this paper. The key step of the method is to set up reference sleepers. This paper made an adjustment scheme for a 500-meter-long ballastless track section as an application case. An evaluation for the scheme was done by considering the evaluation indexes of regularity indexes, rail curvature and vehicle-track system dynamic responses. The evaluation result indicates that the method based on cubic spline interpolation is effective on track profile irregularity adjustment.
