摘要：	Tamping affects track geometry irregularity indexes to different extents. The recovery measure of tamping on different track geometry irregularity indexes plays an important guiding role in the scientific decision making related to tamping operations and for the effective management and control of track quality. In this study, the recovery rates of track geometry quality and track geometry degradation rates between two adjacent tamping operations corresponding to each track geometry irregularity index were used as recovery measure indexes to establish models for the recovery measure of tamping on different track geometry irregularity indexes. Box plots were used for comparative analyses of the recovery effects of tamping on different track geometry irregularity indexes. To verify the effectiveness of these models, a total of 31 track inspection car historical data from September 2014 to December 2016 and tamping operation maintenance data during this time from the Shenmu–Shuozhou railway Hexi transportation division was used. The results showed that the recovery measure models proposed in this study can be used to effectively guide tamping operations. The tamping strategy based on these models helped significantly improve the tamping of the Shenmu–Shuozhou railway in terms of the tamping length of track and tamping cost. This was verified by comparing with the traditional tamping strategy and the tamping strategy based on the longitudinal level.
