Penetration test measures for mechanical characterization of sandy deposits at Scanzano Jonico: geostatistical methods for variability interpretation
Field tests, as static cone penetration tests (CPT), are widely used in granular soilcharacterization because they draw continuous profiles of tip resistance qc and sleeve friction fs.Such measurement profiles are affected by two main sources of uncertainties: (1) measurementerrors and (2) natural variability of soils. Thus, in order to interpret the inherent variability fromCPT measures measurement errors shall be quantified and isolated. Studies and experienceslearned from literature can help to have an idea of the extent of measurement errors whereasexploratory spatial data analysis techniques are needed to practically reduce this sources ofuncertainty before undertaking variability analyses on soils. The case studied concerns CPTsperformed on sandy deposit along Ionian coast in the southern part of Italy in Basilicata Region atScanzano Jonico site. There the outcropping granular deposit is about 20m depth and it is made upof graded sands from the top to the bottom. Lithological boundaries are sought by means of theanalysis of variance technique, that is intraclass correlation coefficient RI method. Therefore thevariability structures related to qc and fs profiles referring to the two sandy soil types recognised,are investigated.
