Abstract

The overarching objective of the Earth Materials and Processes research in this project was to improve understanding of the relationships between low-frequency (sub kHz) electrical properties of soils/sediments and the physical properties determining deformation, strength and failure. The research examined to what extent geotechnical measurements of sediment deformation/failure can be predicted electrical geophysical measurements. The project investigated three hypotheses: [1] Measurable changes in electrical properties will result from variations in effective stress on unconsolidated sediments due to soil matrix compression/expansion; [2] Relationships between electrical properties and soil strength/failure criteria exist due to the mutual dependence of both on the structure of the porous matrix in unconsolidated sediments; [3] Existing models for predicting electrical properties of unconsolidated sediments can be improved by incorporating information on particle shape and orientation; incorporating such effects will improve prediction of mechanical properties from electrical measurements.
