摘　　要：分析了轨道短波平顺性与测量误差的关系,明确了CPⅢ点的误差、无碴轨道调整测量的误差对轨道平顺性的影响,对轨道调整阶段的CPⅢ控制网自由设站边角后方交会进行模拟试验,讨论并验证了相邻测站点相对误差是影响轨道调整精度和平顺性的直接因素。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.
