Abstract
The seismic dilatometer (SDMT) is the combination of the standard flat dilatometer (DMT) with a seismic module for measuring the shear wave velocity Vs. This paper summarizes the experience gained from SDMT tests performed at 34 sites. In particular the paper presents an overview of the SDMT equipment, comparisons of Vs measured by SDMT and by other methods, interrelationships Go, Ed, Mdmt based on 2000 data points and a selection of significant SDMT results and related comments. The paper also illustrates the major issues of present research on use and applications of the SDMT, mostly focused on the development of methods for deriving the in situ G-gamma decay curves and for evaluating the liquefaction resistance of sands based on SDMT results.Pubblicazioni consigliate
