Empirical Correlation Between Electrical Resistivity and Engineering Properties of Soils

Аннотация

Soil's electrical properties are the parameters of natural and artificially created electrical fields in soil and are influenced by distribution of mobile electrical charges, mostly inorganic ions. We aim to determine practically-applicable relations with which to determine soil moisture content and void ratio based on electrical resistivity measurements taken from two different sites in Penang Island. In this study, analysis was conducted to determine the relationship between soil electrical resistivity, moisture content, and void ratio. Moreover, an initial analysis was conducted to determine the variation between the coefficient of gradation with moisture content and void ratio for all data. The developed empirical correlation found in this study can be used as an initial guideline for the further study of tropical soil.
