摘要
站场路基的宽度为单线普通路基宽度的两倍 ,结合青藏铁路试验工程观测的数据 ,分析了冻土区站场路基地温场以及多年冻土人为上限的特征 ,探讨了路基的冻结和融化过程的规律 ,阐述了多年冻土区路基的稳定性问题。
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 analyzes 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.
