摘要
分析了青海地区季节性冻土的冻胀机理,并通过研究毛细理论、Miller第二冻胀理论和分凝冻胀理论,得出冻胀的影响因素,分析表明,季节性冻土冻胀形成的主要因素是负温,提高地表温度将有助于从根源上解决路基冻胀病害的发生。
The thesis analyzes the frost heaving mechanism of seasonal frozen soil in Qinghai region, studies capillary theory, Miller secondary frost heaving theory and segregation frost heaving theory, and obtains frost heaving influencing factors. The analysis shows that： the major frost heaving factor of seasonal frozen soil is minus temperature. Therefore, improving ground surface temperature will be some help for solving sub- grade frost heaving disease.
