Electrical Resistivity Measurements in Advanced Triaxial Tests
A custom made triaxial apparatus that can measure electrical resistivity at any stage of a triaxial test has been developed for determining the feasibility of establishing correlations between electrical resistivity and soil properties. Reconstituted golden flint sand and kaolin clay specimens are tested in consolidated drained (CD) and undrained (CU) conditions, and about fifty measurements of electrical resistivity were made for each test to shed light on how the electrical resistivity changes from specimen mounting to the end of shearing. The results show that electrical resistivity changed on the order of 104 times during the water flushing stage of sand specimens and that resistivity decreases with an increasing degree of saturation. Depending on the soil type, clay or sand, electrical resistivity increases or decreases with an increase in mean effective stress during the consolidation stage. For the investigated soil types, using saturated saline at a defined salt content as the pore fluid, two empirical correlations for predicting the drained friction angle or undrained shear strength are established. These findings imply that the electrical resistivity can work toward advancing characterization of soil properties.
