| 摘 要： | 在季节性冻土区的路基工程中．冻胀是冻害的主要形式之一．冬季较强烈的冻胀也预示着春季可能要产生较严重的融沉和翻浆。根据2000～2002年间对吉林省长余高速公路路基冻张观测所获得的资料．描述了冻胀引起的路面变形破坏特征，对影响冻胀的因素进行了分析．并阐明了路基冻胀量沿冻深的分布状况。

| Abstract: | Frost heaving is one of the main forms of frost damage on the subgrade engineering in the seasonally frozen soil region. The strong frost heaving in winter means that the seirous thawing and settlement and frost boiling may arise in spring. On the basis of the data of subgrade frost heaving observation of Chang Yu Expressway during the year 2000 to 2002, the characteristics of deformation and damage of pavements by frost heaving are described, the factors which influence the frost heaving analyzed and the distributment of the frost heaving amount along frozen depth clarified. |

| Keywords: | seasonally frozen ground region subgrade frost heaving field observation stratified frost heaving amount |
