RESUMO

The world-wide demand for the accomplishment of geotechnical in situ tests is increasing. With th rigorously indicated by the designers for a subsoil identification. The testing method Marchetti Dilatometer (DMT) has being widely used in the world, with different purposes. In this pioneering work with the DMT in Santa Catarina, comparisons between (Standard Penetration Test) and CPT (Cone Penetration Test), already usual in the geotechnical area, had been carried through. The DMT was performed in five different places of Santa Catarina. In the sounding campaigns, CPT and DMT had been carried through and, when available, SPT reports were obtained near the studied places. There is a Mixed-mode Sounding in one place. The soundings campaigns had been performed in the cities of Urussanga, Florianópolis, Tijucas and Antonio Carlos, all of them in the State of Santa Catarina. The attemption of this extention of soils was to analyze the consistency of the collected data by the Marchetti Dilatometer compared with the results of CPT and SPT . This work consists of the collection, analysis and interpretation of the data obtained with the DMT . These results are validated through confrontations with results SPT and CPT in the studied soils. At the end of this research, the conclusion is that the DMT is a promising in situ method to geotechnical research in the Brazilian ground presenting consistent data in the evaluation of estratigraphic profiles and in the search for geotechnical soil parameters. It`s pursuit to introduce commercially the DMT method in the routine of the geotechnical prospection allied to the CPT. The union in field of these in situ tests assorts the devisors more complete results, allowing a bigger agreement of the bulk conditions and thus, define more adequate geotechnical parameters to the conditions imposed by the project.
