This technical report illustrates the first result obtained carrying out a numerical analysis on the suction data measured during a test performed with a physical model of slope. The analysis consists of an interpolation of the measures along a bidimensional domain which corresponds to a vertical cross section of the soil sample. Along each section N. 10 Soil Moisture small tip tensiometers have been placed to measure suction at three different depths.
The main results of this analysis are aimed at identifying how the seepage process takes place inside the soil sample and how it characterizes the sample saturation before failure occurs.
The numerical analysis is carried out using the commercial software Surfer. This software is suitable to make interpolation of data inside a bidimensional or tridimensional domains by means of different mathematical relationships. In this case the method used is the Inverse Distance Weighting (IDW); it is a mode for multivariate interpolation, which assigns values to unknown points by using values from scattered set of known points.
The first result are here discussed.
