| 摘 要： | 针对季节性冻土区高速公路路基受冻害严重影响的情况，对吉林省长平、长营等几条高速公路进行野外冻害调查。取现场钻探土样进行室内冻胀融沉试验，并分析含水率及容重值对冻胀性的影响，进而对高速公路的冻害现象基本有规律性的认识，为季冻区高速公路防冻设计和维护提供依据和相关资料。

Experimental Study on Frost Heave of Highway Subgrade in Seasonal Frozen Region |
| |
| Abstract: | Since highway subgrades are seriously affected by frost damage in seasonal frozen regions, this article investigates the field freezing damage to several highways in Jilin province such as Changchun-Siping highway and Changchun-Yingchengzi highway, carries out indoor frost heaving and thaw collapsing test to field bore plug and analyzes the impact of water content and volume weight to frost heave so as to obtain basic law of highway frost damage and to provide frost-proof design and maintenance basis and data for highways in seasonal frozen regions as well. |
