目的：探讨高填方路基纵向裂缝产生的原因和处理对策。
Objective to discuss the cause of longitudinal crack in high-fill roadbed and treatment countermeasure.
结论：采用压浆技术对高填方路基纵向裂缝进行处理具有良好效果。
Conclusion it has favorable effect adopting the grouting technique to deal with longitudinal crack in high-fill roadbed.
这种差异变形会随着时间加剧，最终导致路基纵向裂缝的发育进而严重影响路基的稳定性。
The deformation difference will be aggravated with time; and finally the embankment stability is affected by longitudinal cracks of embankment caused by asymmetric settlement of permafrost.
