黄土的视电阻率与工程性质关系研究

Study of the Relationships Between Apparent Resistivity of Unsaturated Loess and Its Engineering Properties

对黄土进行了视电阻率试验,分析了视电阻率与黄土一般物理性质、湿陷性及强度等特性之间的关系。应用因子分析法对视电阻率及其它物理力学指标之间的关系进行了深入的探讨,对各指标的重要性(以贡献率表示)进行了分析。研究结果表明,视电阻率的重要性最大,高于含水率、密度、压缩系数及湿陷系数等指标。

Experiments on apparent resistivity, moisture content, density, compressibility, strength, collapsibility of unsaturated loess were performed in laboratory. Testing data were analyzed using correlation analysis model. The relations of apparent resistivity to moisture content, density, compressibility, strength, and collapsibility of unsaturated loess were analyzed using the factor analysis method. Results showed that the contribution of the apparent resistivity was greater than those of moisture content, density, compressibility, an collapsibility of unsaturated loess.
