摘要
季节性冻土的冻融过程不仅依赖外部因素,还与路基本身的组成有着密切的关系。西藏藏东南地区以季节性冻土为主,研究其冻胀—融沉形成机理与影响因素,为藏东南季节性冻土区道路工程设计、施工提供参考。
the thawing process of the seasonal permafrost not only depends on external factors,but also has a close relationship with the the composition of roadbed itself. Seasonally frozen soil dominates in Southeast of Tibet,studying its heaving-thaw formation mechanism and influence factors provides a theoretical reference for engineering design and construction of seasonal permafrost zone in southeastern Tibet road.
