非饱和土的应力传递机理与有效应力原理

Stress transmission mechanism and effective stress principle of unsaturated soil

回顾了几十年来非饱和土有效应力研究的主要成果。根据非饱和土的应力传递机理 ,提出了土样中任一点三个有效主应力表示形式和有效应力参数确定方法。

The main research results of effective stress principle of unsaturated soil several decades are reviewed. Based on the study of stress transmission mechanism of unsaturated soil, the description of three main effective stresses and the determination of effective stress parameters are also pressented at any point in unsaturated soil body.
