Study on Electrical Resistivity Characteristics and Influencing Factors of Soil-Stone Composite Medium

Abstract:

At present, there are only a few theoretical models for researching the electrical resistivity characteristics of multi-phase soil-stone composite medium, as it could be influenced by so many factors. Based on the theory structure models of unsaturated soil electrical resistivity put forward by previous researchers, a theoretical model of multi-phase soil-stone composite medium electrical resistivity properties, suitable for both series connection structure and parallel connection structure of soil stone mixture, is proposed, through which the regular patterns under the influence of water content, porosity, soil-rock ratio, and saturation are analyzed. In line with the results, when the composition of particles are not changed, in the order of sensitive, the main factors that affect electrical resistivity characteristics are water content, porosity, and soil-rock ratio.
