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 paper analyses the character of yard-and-station roadbed's temperature field and artificial permafrost table,also discusses the rule of the process of embankment's freezing and thaw. The stability of embankment in permafrost region is also presented.

Key words

permafrost / yard-and-station roadbed / temperature field / artificial permafrost table
