Abstract: Based on experimental test of electrical resistivity of polyphase soil-rock samples,the relationsip between electrical resistivity and physical parameters,such as soil-rock ratio and compaction properties and moisture content of polyphase soil-rock mediums,was analyzed. The electrical resistivity equation of polyphase soil-rock mediums was proposed and it was the same form as Keller equation on unsaturation soil electrical resistivity. The research results indicated that the electrical resistivity equation of polyphase soil-rock mediums could be analyzed by taking Keller equation after taking the influence of soil-rock ratio for soil indicators and cementation coefficients and saturation exponents into consideration.
Key words: polyphase mediums, soil-rock mediums, electrical resistivity
摘要: 在对大量多相土石复合介质试件的电阻率测试试验基础上,分析了土石复合介质土石比、压实特性、含水量 等参数对电阻率的影响规律;基于试验数据的统计分析,给出了多相土石复合介质电阻率方程,该方程与Keller非 饱和土电阻率方程具有完全相同的结构形式。研究表明:多相土石复合介质电阻率随含水量的增加呈幂函数衰 减,随击实次数的增大而减小,随含石量的增大而增大;在相同条件下对电阻率的影响以含水量最为敏感、击实次 数和含石量次之;在考虑含石量对土性参数、胶结系数以及饱和度指数的影响后,多相土石复合介质电阻率特性完 全可以用Keller非饱和土电阻率方程来描述。
