土体电阻率模型研究现状综述

Review of soil resistivity model

本文从土体的导电性和Archie公式着手介绍了电阻率基本理论,调查了目前土体电阻率的主要测定方法以及常见的仪器设备,深入分析了土体电阻率的主要影响因素,对多种土体的电阻率模型及其应用现状进行归纳总结.结果表明,国内外区域性特殊土类电阻率模型构建研究较少,已有的不同土类电阻率模型使用参数存在较大差异,缺乏统一的电阻率测试方法,基于电阻率测试的土体物理力学性质的定量化评价研究不够深入,旨在为土体电阻率模型构建相关研究提供参考.

This study introduces the basic theory of resistivity based on the soil conductivity and Archie’s formula, investigates the current main measuring resistivity methods and common instruments, and the main influencing factors of soil resistivity are analyzed. The multiple soil resistivity models and applications were reviewed. The results show that there are less research on the construction of regional specific soil resistivity models, the parameters used in the existing resistivity models are quite different, and lack of unified resistivity testing method.The quantitative evaluation of soil physical mechanical properties is insufficient, aims to provide a reference for other related research work on soil resistivity model.
