摘要

本文首先较详细一讨论了一般粘土(“结构强度”的影响可以忽路)和有“结构强度”粘土的压密状态.区分先期固结压力和结构屈服压力不同的物理实质

澄清二者之间的差别并指出混淆这种差别可能引起对土的压密状态的分析和力学性质的估计的错误.其次

讨论了土的结构强度

压密状态和压密性质之间的关系.最后

讨论了土的结构强度、压密状态和抗剪强度的关系.揭示了孔隙水压力变化的规律.

Abstract

This paper discusses in detail compacted states of common clay (the effect of the structural strength can be negiligible) and clay possessing structural strength. The physical essence of preconsolidation pressure is distinguished from that of structural yield pressure. The difference between them is demonstrated. It is pointed out that improper interpretation their difference may cause froubles in analyzing compactibility of clays and evaluating their mechanical properties. The relationship among structural strength

compactibility

and shear strength of clays is discussed

and some phenomena of pore-water pressure change are presented.
