Abstract

In the last decades there has been a massive migration from laboratory testing to in situ testing, to the point that, today, in situ testing is often the major part of a geotechnical investigation. In particular direct‐push in situ tests, such as Cone Penetration Test (CPT) and the Flat Dilatometer Test (DMT), are fast and convenient in situ tests for routine site investigation. The scope of this paper is to describe the DMT and its recent updates, in particular the Seismic Dilatometer Test (SDMT) for measuring shear and compression wave velocities and the automated dilatometer probe (Medusa DMT). An Example of SDMT test results and its application to derive soil stiffness parameters are shown, as well as the result of a class‐A prediction of an anchor pull‐out test, which was calibrated with the SDMT profile.
