| 摘 要： | 通过野外原位观测发现,在北半球自然气温条件下,地表裸露、原状均质、冻胀性地基土的冻结过程中,冻结速率越大越有利于土的冻胀,即冻结速率与冻胀速率呈单值升函数规律.

| Abstract: | 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. |

| Keywords: | temperature gradient freezing rate frost-heaving rate frost heaving ratio |
