摘要

土力学传统理论认为，土的先期固结压力受控于应力历史，与曾经受到的压力有关。然而，通过室内试验发现，红黏土这类区域性特殊土的先期固结压力所表现出的规律与传统理论相悖。研究表明，红黏土的先期固结压力主要受土的成因、结构和成分制约，上覆压力对其影响甚微。笔者分析了土力学传统观点在解释红黏土特性时存在的缺陷，探讨了红黏土先期固结压力的真正含义，提出了对红黏土先期固结压力的新认识。

Abstract

The traditional theory of soil mechanics considered that the preconsolidation of soil was controlled by the pressure force and stress history. However

based on the experimental results

the rule of the preconsolidation of red clay that is territorial peculiar soil is different from the traditional theory. The studies show that

the preconsolidation of red clay is most constrained by soil genesis

structure and component

and is affected by the overlying pressure in little degree. Finally

the defect of traditional soil mechanical view on red clay is analyzed; and the genuine signification of preconsolidation pressure of red clay was studied; and the new understanding about the preconsolidation is presented.
