土的冻胀机理研究

一个多世纪以来人们对有关土的冻胀机理问题进行了大量的实验和研究,提出了很多假设,取得了很大的成果。文中从土的冻胀特性入手提出了"起始冻胀力"、"冻胀-抽吸力"等新概念,并提出了冻胀力才是冻结过程中水分迁移的驱动力的新概念。

A STUDY ON THE MECHANISM OF FROST HEAVY OF SOIL

In the past more than a century,a lot of experiments and researches have been done on the frost heaving mechanism of soils,put forward numerous hypotheses and a lot of great achievements have been made.In this paper,the new concept of "initial frost heave force","frost heave-suction force" is put forward from the frost heaving characteristics of soil,and the frost heaving force is proposed as the driving force of water migration during freezing.
