A Miniature Falling Weight Device for Non-Intrusive Characterization of Soils in the Centrifuge

Non-intrusive and non-destructive techniques are used for characterizing multilayer soil models in the centrifuge. Based on the spectral analysis surface waves analysis, a miniature falling weight-type (FW) device is developed for centrifuge testing. A description of the mini-FW with application to characterize homogeneous and bilayer models is presented. The mini-FW principle consists of the fall in a steel ball generating vibrations within the centrifuged models. These vibrations are recorded by accelerometers placed on the model’s surface. On condition that the vibrations remain within the first 5 upper centimeters in order to avoid near-field effects, the results obtained for both wave velocity values and location of the layer interfaces agree satisfactorily with already available data.
