| Abstract: | We analyze the relationship between track regularity and measurement error,and demonstrate the impact of errors form CPⅢ measurement and ballastless-track adjustment on the track. Using a simulation experiment on the Free-station Linear-angular Intersection of CPⅢ horizontal control network during phase of track adjustment,we discuss and validate the relative error of adjacent station points is the direct factor of accuracy of track adjustment and regularity. |
