Abstract

The paper presents the geotechnical characterization of a clay soil subjected to a preloading embankment for the construction of an industrial electronics building in the industrial area (STM M6) of Catania (Sicily, Italy). To determine the geological profile and the geotechnical characteristics of the soil, the site was well investigated by means of in situ and laboratory tests. The following in situ geotechnical tests were carried out: Borings, SPT, CPT, PLT and dynamic in situ tests have been performed. Among them Down-Hole (D-H), Cross-Hole (C-H), SASW and recently Seismic Dilatometer Marchetti Tests (SDMT) have been carried out, with the aim to evaluate the soil profile of shear waves velocity (Vs). Moreover the following laboratory tests were carried out on undisturbed samples retrieved with a 86 mm diameter Shelby sampler: Oedometer tests, Direct shear tests, Triaxial Tests, Resonant Column and Torsional shear tests. Static and dynamic parameters were compared by in situ and laboratory tests. A significantly correspondence between the values of the geotechnical parameters derived from laboratory and in situ tests was observed. The in situ and laboratory geotechnical analysis gives the parameters to evaluate the performance of soil subjected to soil embankment by mathematical modeling.

Geotechnical Characterization of a Soft Clay Soil Subjected to a Preloading Embankment

Arlington, Virginia

The paper presents the geotechnical characterization of a clay soil subjected to a preloading embankment for the construction of an industrial electronics building in the industrial area (STM M6) of Catania (Sicily, Italy). To determine the geological profile and the geotechnical characteristics of the soil, the site was well investigated by means of in situ and laboratory tests. The following in situ geotechnical tests were carried out: Borings, SPT, CPT, PLT and dynamic in situ tests have been performed. Among them Down-Hole (D-H), Cross-Hole (C-H), SASW and recently Seismic Dilatometer Marchetti Tests (SDMT) have been carried out, with the aim to evaluate the soil profile of shear waves velocity (Vs). Moreover the following laboratory tests were carried out on undisturbed samples retrieved with a 86 mm diameter Shelby sampler: Oedometer tests, Direct shear tests, Triaxial Tests, Resonant Column and Torsional shear tests. Static and dynamic parameters were compared by in situ and laboratory tests. A significantly correspondence between the values of the geotechnical parameters derived from laboratory and in situ tests was observed. The in situ and laboratory geotechnical analysis gives the parameters to evaluate the performance of soil subjected to soil embankment by mathematical modeling.
