中文摘要：
通过对重塑膨胀土的电阻率进行测试研究,提出了一种饱和/非饱和土的假想电阻率模型。研究表明：膨胀土的电阻率主要与土骨架、孔隙水的电阻率以及膨胀土的含水率、饱和土度和孔隙比等有关。研究提出了用土的水体积比表征膨胀土的电阻率特性,研究建立了电阻率–水体积比与吸力–水体积比（水分特征曲线）之间的关系,以探索研究电阻率的应用。
英文摘要：
The electrical resistivity of the remold expansive soils was studied and a pseudo-electrical resistivity model of the soil was presented. It was demonstrated that the electrical resistivity of remold expansive soils was a function of the electrical resistivity of soil skeleton and pore water, water content, degree of saturation and void ratio of soil, etc The volumetric ratio of water in the soil, defined as the ratio of the volume of water in the sample to the total volume of the sample, was used as the controlling parameter. The relationship of matric suction-ratio of water volume was observed to be similar to the electrical resistivity-ratio of water volume. The measurement of the electrical resistivity method was shown to be satisfactory for investigating the behavior of expansive soils. Because the method was relatively easy to be used, it was actually advantageous.
