Abstract
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 subgrade frost heaving disease.
