At present time, most savants consider that small freezing rate was advantageous to frost heaving. Through in situ observation, it was found that great freezing rate was more advantageous to frost heaving under natural air temperature of north hemisphere for exposed homogeneous subsoil, which is able to heave, i.e., frost-heaving rate increases with freezing rate.
