摘要
采用伏安法对50Hz低频交流电下的土体电阻率进行测量,测试结果数据表明电阻率的值与温度,含水率,干密度有关,随着温度变化变大,而负温情况下电阻率随含水率先减小后增加,随着干密度增加线性减小。
The resistivity of soil under low frequency alternating current of 50Hz is measured by voltammetry. The results showthat the resistivity is related to temperature, water content and dry density, and increases with the change of temperature. Under neg-ative temperature, the resistivity decreases first and then increases with water content, and decreases linearly with the increase of drydensity.
