Abstract
Advanced triaxial testing in unsaturated soils includes local strain and suction measurements. However, in unsaturated soils, the complete local determination of the state of the specimen also requires the monitoring of local changes in water content. To this aim, a new electrical resistivity probe, composed of two pairs of electrodes was developed. Some experimental data on the changes in resistivity with the degree of saturation were obtained by carrying out calibration tests in specimens of natural unsaturated loess from Northern France. Two resistivity models were also used to analyze the obtained data. Results are finally discussed with respect to the loess’s water retention properties.
