Abstract:

This paper presents the results of a series of Flat Marchetti's Dilatometer Tests (DMT's) performed in a large Calibration Chamber (CC) on dry Ticino (TS) and Hokksund (HS) sands. These results, together with those of similar earlier tests discussed S. Marchetti, are evaluated to assess the capability of DMT, for determining the coefficient of earth pressure at rest, K//o, and deformation parameters of the natural sand deposits.
