摘要：
The soil samples of the roadbed slope of the Datong-Xi'an high-speed railway section are taken as the research object. The frost-heave property of the fiber soil of the roadbed slope under a single freeze-thaw cycle is studied, where the fiber's content is taken into account. The distributions of temperature and humidity fields inside the slope are numerically studied, and the coupling transfer of heat and moisture is revealed. The results are helpful for the optimal design of the roadbed slope.
