多相土石复合介质电阻率特性由于影响因素较多,目前对于其理论模型研究较少.在前人提出的非饱和土电阻率结构模型的基础上,基于土石介质串联和土石介质并联两种结构形式,建立了多相土石复合介质电阻率结构模型,并分析了含水率、孔隙率、土石比和饱和度对土石复合介质电阻率特性的影响规律,结果表明:当土石颗粒本身的成分不变时,影响土石复合介质电阻率特性的主要因素有含水率、孔隙率、土石比三个因素,其敏感程度从大到小依次为含水率、孔隙率和土石比.

@@@@Because the electrical resistivity of multi-phase soil-stone composite medium is influenced by so many factors , there are only few studies about the theoretical model of this medium .On the basis of existing structure models of unsatu-rated soil’s electrical resistivity ,the structure model for the electrical resistivity of multi-phase soil-stone composite medi-um is established based on both the series connection structure and parallel connection structure of soil stone mixture .The influence laws of water content ,porosity ,soil-rock ratio and saturation on the electrical resistivity are analyzed .The re-sults show that when the composition of soil-stone particles are not changed ,in the order of sensitivity ,the main factors that affect the electrical resistivity characteristics are water content ,porosity and soil-rock ratio .
