DMT-predicted vs measured settlements under a full-scale instrumented embankment at Treporti (Venice, Italy)

This paper presents the preliminary results of field studies based on data from flat dilatometer tests (DMT) and the comparisons of measured vs DMT-predicted settlements. The study is part of a research project aimed at the characterization/modeling of the Venetian soils. A key feature of the project was the construction of a full-scale instrumented embankment (40 m diameter, 6.7 m height, applied load = 104 kPa) at the site of Treporti. The soil, typical of the Venice lagoon, is highly stratified and remarkably non homogeneous. Deformation moduli M obtained from DMT were used to predict settlements by using the "traditional" 1-D approach.
