New developments on the Flat Dilatometer (DMT) and Seismic Dilatometer (SDMT) for geotechnical and geophysical in situ testing

Diego Marchetti

The aim of the presentation is to describe the current state of art of the Flat Dilatometer (DMT) and Seismic Dilatometer (SDMT) technology for soil characterization and the new recent development Medusa DMT. The working principle, test procedures, interpretation of geotechnical parameters and the main engineering applications will be illustrated for this testing equipment used in over 80 countries worldwide. Comparisons of results with other soil investigation instruments will be shown in well documented research test sites.
