Comparisons CPT-DMT in soft clay at Fucino-Telespazio GeoTest site

This paper presents the comparison of results obtained from CPT/CPTU tests carried out in past investigations and from recent DMT tests carried out using the automated Medusa DMT, adopting different test procedures (standard, repeated A-readings, A-reading while penetrating), at the benchmark soft clay test site of Fucino-Telespazio, Italy. In particular, the depth profiles of the undrained shear strength su of the Fucino clay obtained from CPT/CPTU interpretation are compared with the su profiles obtained from standard DMT and from Medusa DMT using different test procedures, as well as with the su values obtained from field vane test (FVT), self boring pressuremeter test (SBPT) and laboratory tests available from past investigations, resulting generally in good agreement.
