| Abstract: | The width of yard-and-station roadbed is twice over common single-track embankment. Based on the experimental data of Qinghai-Tibet railway's experimentation project, the character of yard-and-station roadbed's temperature field and artificial permafrost table are analyzed, the rule of the process of embankment's freezing and thaw is also discussed. The stability of embankment in permafrost region is also presented. |
