The occupation of areas with soft soils is becoming common. Deposits of this type are characterized by its low bearing capacity and high compressibility. Due to the high cost of treatment of the foundation in deposits with these characteristics, it is necessary to know the geotechnical behavior of the subsurface more accurately, in order to optimize engineering solutions.This study aimed to identify the geotechnical parameters of a deposit of soft clay located in the area known as Ilha da Madeira, Baia de Sepetiba in Itaguaí-RJ. The interpretation of geotechnical investigations carried out previously in the area, involving laboratory tests (characterization tests, triaxial and consolidation) and field tests (piezocones with measures of increased pore pressure - CPTu, vane tests and boreholes tests), was performed. To evaluate the results of tests 11 investigations islands were defined. Furthermore, the quality of the samples was evaluated. The geotechnical parameters obtained from the interpretation of the tests proved consistent with the values reported in the literature, for deposits of soft clays from the state of Rio de Janeiro.
