季节性冻土由于其冻胀、冻融作用对公路路基、路面产生了一定的影响，尤其是东北高纬度严寒地区，这种现象对公路稳定性的影响更大。本文根据国内外有关研究成果，结合工程实例，对冻胀的机理及处治措施进行了分析与探讨。
季節性凍土由于其凍脹、凍融作用對公路路基、路麵產生瞭一定的影響，尤其是東北高緯度嚴寒地區，這種現象對公路穩定性的影響更大。本文根據國內外有關研究成果，結閤工程實例，對凍脹的機理及處治措施進行瞭分析與探討。

Seasonal frozen soil has a certain influence on highway roadbed and road surface due to the frost heaving and freeze-thaw function. Especial y in the northeast cold region at high altitudes, this phenomenon has a greater influence on the stability of highway. According to the relevant research results at home and abroad, combines with the engineering instance, this article analyzes the frost heaving mechanism and disposal measures.
