Abstract (EN): An extensive site investigation has been made in a relatively homogeneous weathered profile of a typical saprolitic soil from granite of Porto region, which included penetration testing such as DP, SPT and CPT, pressuremeter (PMT and SEPT), dilatometer (DMT), cross-hole seismic testing (CH) and Loading Tests (PLT over 30 and 60cm diameter plates and a 120cm diameter concrete footing, carefully instrumented). Identification and classification based on such testing methods and criteria of interpretation of the results in order to define mechanical properties and geotechnical design parameters-mainly for shallow foundations purposes-are discussed. Most attention is made on the adaptation of current criteria for evaluation of geotechnical properties, developed for transported soils with similar physical properties, to the particularities of these residual soils, characterized by singular fabric and structural (cementation) characteristics.
