This thesis consists of a study of stress-strain-strength behavior of the compacted embankment constructed behind the experimental tire wall located in Jacarepagua (Rio de Janeiro). The experimental wall has four sections with differet characteristics. From these, two were chosen for the field tests and for extraction of undisturbed samples. Dilatometer and pressuremeter were accomplished in the field, together with characterization, consolidation and shear resistance tests in the laboratory. The experimental program in the laboratory consisted of direct shear on specimens with natural moisture content and submerged conditions. Conventional triaxial test and special stress path tests were also performed under drained conditions. Detailed description of the methodology and interpretation of all tests are presented in this work, together with a discussion of the results. In particular, the discussion focussed on the values of in situ stresses (coefficient of lateral stress at rest) and of the stress-strain modulus (Young's modulus, Poisson ratio, shear modulus). The shear strength characteristics were also analyzed, considering both natural humidity and totally saturated specimens. From the most significant conclusions, it can be pointed out that the compacted material was shown to be slightly overconsolidated, with values of OCR smaller than 2 and k0 in of the order of 0,68 to 0,70. The differences between field and laboratory values are also discussed in the thesis.
