中文摘要：

通过测试原状黄土固结过程中的电阻率,研究了固结压力和电流频率对电阻率参数的影响规律。结果表明：原状黄土固结过程中,随着压力的增大,横向电阻率增大,竖向电阻率、平均结构因子、平均形状因子和各项异性系数先减小后增大;随着电流频率的增大,平均结构因子和平均形状因子先快速下降后逐渐趋于平稳,各向异性系数先快速上升后缓慢上升;建议类似研究的电流频率范围采用50 k Hz~1 MHz为宜。

英文摘要：

The effects of the consolidation pressure and current frequency on electrical resistivity parameters were studied via measuring the electrical resistivities during consolidation test of undisturbed loess. The results show that,with the increasing of pressure,the horizontal resistivities increase whereas the vertical resistivities,average structure factors,average shape factors and anisotropic coefficients firstly decrease and then increase. With the increasing of current frequency,the average structure factors and average shape factors firstly decrease rapidly and then keep stable,but the anisotropic coefficients firstly increase rapidly and then increase slowly. A reasonable range of current frequency is recommended as 50 k Hz - 1 MHz.
