摘要
为深入了解赤泥的电阻率特性,对赤泥电阻率进行了室内试验。通过测试不同含水率、不同孔隙率、不同龄期的赤泥在不同电流频率下的电阻率和赤泥的无侧限抗压强度,研究分析了电阻率与各变量之间的关系。研究表明:赤泥电阻率随电流频率、含水率、轴向应变的增加呈减小趋势,随龄期的增加先增大后减小,随孔隙率的增加先减小后增大,各因素相互影响,共同作用。
For a better understanding of the electrical resistivity characteristics of the red mud,the electrical resistivity tests on red mud were made in laboratory.The red mud electrical resistivity and unconfined compressive strength were measured with different water contents,porosities,and ages under different current frequencies.The relationship between electrical resistivity and each variable was studied.Results show that,the red mud electrical resistivity decreases with the increase of current frequency,water content and the axial strain;it first increases then decreases with the increases of age,which is in contrast to porosity;factors affect each other and work together.
