无砟轨道工程长钢轨静态调整中的中长波控制

The middle and long wave control of ballast-less track engineering in long steel static adjustment

通过引入中长波不平顺(50 m,80 m弦)的控制理念,根据多条已开通线路无砟轨道静态调整和联调联试经验,确定轨道高低、轨向50 m,80 m弦中长波不平顺的管理建议值,使得轨道平顺性得到全面的控制,进一步提高了轨道的平顺性、舒适性和安全性。

Through the introduction of control theory of middle and long wave irregularity （50 m, 80 m string）, according to ballast-less track static adjustment and debug integration test experience of many already opened circuits, determined the management recommendation values of track high-low, track direction 50 m, 80 m string middle and long wave smooth-less, made the track smoothness control to obtain comprehensive control, further improved the smoothness, comfort and safety of track.
