| 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。

| Abstract: | 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. |

| Keywords: | cemented soil strength electrical resistivity average structure factor average shape factor anisotropy factor |
