Characterization of structured soils by in-situ tests cannot be interpreted with success by applying the common methodologies dedicated to sedimentary soils, due to the presence of cemented structures that deeply influences the correspondent mechanical behaviour, deviating from Classical Soil Mechanics concepts. From the shear strength point of view, structured soils are represented by two parameters that have to be derived simultaneously (cohesion intercept and angles of shearing resistance), which is only possible to achieve in tests that measure more than one parameter, such as DMT, CPTu or PMT tests. In its turn, deformability of structured soils is characterized from 2 yield points, one related with beginning of yield weak bonds (first yield) and another one related with the more or less complete breakage of the bond structure (bond yield or gross yield), which are not present in non-structured soils. As consequence, moduli decay curves are more pronounced than those typically displayed in sedimentary soils. In this context, the research carried on in Portuguese granitic environs tested by (S)DMT has shown its usefulness in the characterization of these structured materials both because the possibility of identification of cemented structures and the adequate strength and stiffness parametrization. The whole research frame included several sites (in Porto and Guarda granites) with CPTu and DMT tests performed in pairs, supported by laboratorial testing and by the information integrated in the Porto Geotechnical map, a calibration apparatus where DMTs were performed in artificially cemented soils closely controlled by laboratorial tests and several sets of SDMT, PMT, CPTu and triaxial tests performed in a high quality experimental site (IPG). The accumulated experience, interpretation methodologies and obtained correlations arising from these experimental frames will be summarized and discussed in the present paper.
