摘要
根据有效应力原理和土体超固结比的定义,阐述了先期固结压力和土体现有上覆竖向压力均应为有效应力。基于固结理论,指出处于欠固结状态土体的超固结比应等于1而非小于1。
The paper expounds that the preconsolidation pressure and current overburden vertical pressure of soil should be the effective stresses according to the principle of effective stress of soil and the definition of over-consolidation ratio.Based on the consolidation theory,it points out that the over-consolidation ratio of the underconsolidated soil should be equal to 1,not less than 1.
