The role of geophysical methods in geotechnical and geo-environmental site characterization is continuously increasing thanks to technical improvements and decreasing costs of recording instrumentation. Moreover advances in computational capabilities and refinements in interpretation methods have indeed increased their capabilities and reduced the uncertainties in the interpretation.
A wide range of methods is available to reconstruct geometrical features of the subsoil accounting for different responses of soils as a porous medium and for the characteristics of the pore fluid. Seismic tests provide moreover the advantage of a direct evaluation of the mechanical response of the medium, although only at very small strain levels, with the possibility of testing geomaterials in their undisturbed state on site.
In the webinar, after an introduction of the typical applications, the most common geophysical test will be presented with focus on their capabilities and limitations. Some case histories will be presented to discuss the selection of appropriate methods with respect to the target of the characterization. Finally the advantages arising from the combination of different methods will be introduced and discussed.
