Influence of petrophysical and geotechnical engineering properties on the electrical response of unconsolidated earth materials
We have investigated the influence of petrophysical and geotechnical engineering properties of unconsolidated near-surface geomaterials (soils) on their electrical responses or measurements. Complex resistivity measurements were performed at a constant effective stress on 32 samples of varying textures and compositions. Petrophysical and engineering properties that inherently affect the mechanical and strength behavior of the samples - that is, fines content, pore-size parameter, specific surface area, and fractal dimension of the grain-size distributions - were obtained from geotechnical analysis. The electrical parameters that describe the electrical response of the samples - that is, resistivity amplitude , phase shift , percent frequency effect (PFE), loss tangent tan δ, and the normalized phase
