摘要

在讨论黏性土导电特性的基础上，假定非饱和黏性土中存在3种电流流通路径，针对已有的非饱和土电阻率结构模型存在的缺陷，推导了适用于非饱和黏性土的电阻率结构模型，探讨了土电阻率的主要影响因素，并将其归纳为3类。最后，通过对合肥膨胀土相关试验研究，分析了含水率、孔隙水电阻率、温度以及孔隙率对膨胀土的电阻率的影响特征，探讨了非饱和膨胀土的电阻率基本特性。

Abstract

Electric current flows through clayey soils by the conduction of void water

electric double layer and clay minerals. The electrical characteristics of clay are discussed at first. Based on the hypothesis that there are three conductance pathways in unsaturated clay

and aiming at the deficiency of the existing models of unsaturated clayey soil

the electrical resistivity model of unsaturated clayey soil is studied. The main factors which affect the electrical resistivity of soils are summarized and analyzed. Through the laboratory tests

the characteristics of the influences of water content

the resistivity of pore fluid

temperature and porosity on the electrical resistivity of Hefei expansive soil are studied.
