地基土冻胀的宏观分析

Macrograph Analysis about Subsoil Frost Heaving

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 。

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.
