The seasonal frost damage of subgrade is common at present. The paper introduces the arrangement principle of unwatering hole in the treatment design thereof; and through analyzing the change characteristics of temperature and moisture fields at the soil mass of subgrade around unwatering holes, the actions of unwatering, drainage, evaporation and air drying of such holes are revealed.
