冻土路基可能存在的冻胀破坏,文章对冻土现象的成因及其影响因素进行了分析,并提出了利用冻胀引诱处理冻土对路基的损坏。在理论上,通过调节路基内外的温差和控制膨胀发生在预留膨胀室内,能够有效地防治冻土地区路基的破坏,为解决冻胀问题提出了新的解决思路。 The possible causes of frost heaving damage on the permafrost embankment are analyzed in this paper. The causes of permafrost phenomena and their influencing factors are analyzed in this paper. The damage caused by the frost heave on the subgrade is also proposed. In theory, by adjusting the temperature difference inside and outside the embankment and controlling the expansion occurred in the reserved expansion chamber, it can effectively prevent and treat the destruction of roadbed in permafrost region, and put forward a new solution to the problem of frost heaving.
