摘要
非饱和土的抗剪强度有三个组成部份:真凝聚力、摩擦强度和吸附强度。本文分析论述这三个组成部份的来源、特性及其变化规律。 根据一系列研究试验的结果,笔者提出以下三种相互关系的计算公式并讨论了有关的概念:①粘土内摩擦角与塑性指数的相互关系;②吸附强度与膨胀压力的相互关系;③膨胀压力与吸力的相互关系。
Shear strength of unsaturated soils is composed of three components: true cohesion, friction and suction strength. Their nature and characteristics are analysed. Based on series of tests, formulas on the reletionships between: (1) angle of internal friction and plastic index, (2) suction strength and swelling pressure, (3) swelling pressure and suction force are presented.
