摘要
采用电阻率测试技术,通过测试水泥土在强度增长以及压缩过程中的竖向、水平向电阻,探求水泥土在强度增长过程和压缩过程中电阻率特性参数——平均结构因子F、平均形状因子f以及各向异性系数A变化的基本规律,分析了F,f,A与水泥土物理力学特性之间的关系,证实了这3个参数能对土的结构性进行定量分析。
The electrical resistivity testing technology is presented to research the structural characteristics of cemented soil quantitatively, To describe the change of the resistance, three electrical resistivity indices： average structure factor F, average shape factor f and anisotropy factor A; are introduced. With the measure of vertical and horizontal resistance during the compression test, the electrical resistivity indices of cemented soil are concluded. Then, the relationship between the electrical resistivity indices and physico-mechanical characters is analyzed. The results show that it is effective to research the soil structure by the electrical resistivity indices.
