摘要

通过开展固结压缩试验

研究了超固结比（OCR）对海相沉积软黏土热固结特性的影响。试验结果表明:加温可能使软土发生沉降或回弹。在OCR较小的情况下

加温将使软黏土产生沉降;OCR越小

温度效应导致的沉降量越大

降温后回弹较少。在OCR较大的情况下

加温将使软土产生膨胀;降温后膨胀可部分恢复

且OCR越大恢复量越大。在此基础上

根据测试结果拟合了考虑OCR影响的热固结经验关系式。该式可用来预测不同应力状态条件下软土应变随温度变化的关系。

Abstract

A series of thermal consolidation compression tests were carried out in this paper.The effect of over consolidation ratio（OCR）on the thermal consolidation characteristics of typical soft clay in Ningbo area was studied.The results show that heating may cause settlement or rebound of soft soil.In the case of small OCR

heating will cause soft clay to subside

and the smaller the OCR

the larger the settlement

and the lesser rebound after cooling.When the OCRis large

the heating will cause the expansion of soft soil.The expansion will partially recover after cooling

and the larger the OCR

the greater the recovery.Based on the test results

the empirical relationship of thermal consolidation considering the influence of OCR was fitted.This formula can be used to predict the relationship between strain and temperature of soft soil under different stress conditions.
