摘要

通过对含盐冻结粉质黏土进行三轴压缩试验，分析了该土质在加载至破坏过程中的应力-应变行为，并利用Duncan-Chang双曲线模型求得冻结盐渍粉质黏土的初始弹性模量和偏主应力的最大值。结果表明，初始弹性模量和偏应力最大值随着含盐量的减小和温度的降低而增加。为了分析含盐量对土体强度的作用机制，提出了“相对温度”这一概念，给出相对温度和抗压强度间的线性关系。以一综合指标“相对温度”来考虑盐分、试验温度等多种因素对冻土特性的影响，建立盐渍土和非盐渍土的关系，从而用非盐渍土的力学性质研究盐渍土的力学性质。

Abstract

According to results of the triaxial compressive test of saturated saline frozen silty clay

the stress-strain relationships are studied in the process from the beginning of test to the soil samples destroyed. And maximum values of initial elastic modulus and principal deviator stress are calculated by using Duncan-Chang hyperbolic model. The results show that the values of initial elastic modulus and principal deviator stress increase with salinity reducing and temperature falling. In order to analyze the action mechanism of salt content affecting on soil strength

a new concept

the relative temperature

is put forward

and the linear relationship of the relative temperature and the compressive strength are described. The relative temperature is an integrative conception to take into account how some elements

i. e. salinity

test temperature

etc

affect frozen soil characteristics

so as to express the relationship of saline soil and non-saline soil by the relative temperature. And the mechanical characteristics of saline soil is studied by it of non-saline soil.
