Evaluation methodology for obtaining geotechnical parameters using electrical resistivity

For any type of construction it is necessary to accurately determine the parameters of characterization, permeability and resistance-deformation of the soil. That analysis is carried out with laboratory tests on samples extracted during the geotechnical field investigation. The advantage of this method is the direct measurement of more important properties controlling the environment and contour conditions. Although the process of extracting the samples tries not to modify the initial conditions of the soil, the intervention of the test generates changes in the initial structure, thus the results cannot fully represent the real conditions in the field.
