1. Equipment cubic triaxial for rehearsals in saturated soils and no saturated with suction controlled matric / Equipamento triaxial cúbico para ensaios em solos saturados e não-saturados com sucção matricial controlada
In tropical countries, like Brazil, soils in non saturated condition are frequently encountered. Besides, the majority of geotechnical works load the ground according to stress paths in which the three principal stresses are different and vary independently. Therefore, the need to develop equipments able to test in the laboratory non saturated soil samples f

2. EXPERIMENTAL STUDY OF THE STRESS INFLUENCE ON PERMEABILITY OF PRODUCING OIL ROCKS / ESTUDO EXPERIMENTAL DA INFLUÊNCIA DE TENSÕES NA PERMEABILIDADE DE ROCHAS PRODUTORAS DE PETRÓLEO
Hydrocarbons reservoirs are dynamic systems that constantly changes during depletion. The production of fluids from a reservoir often reduces pore pressure such that there is an increase in its effective stresses. This may cause compaction which, in turn, may impact matrix permeability. On the other hand, during water injection on reservoirs, the pore pressu

3. STRESS - STRAIN BEHAVIOR OF A GNEISS RESIDUAL SOIL USING THE CUBIC TRIAXIAL CELL / COMPORTAMIENTO TENSIÓN X DEFORMACIÓN EN SUELOS RESIDUALES / COMPORTAMENTO TENSÃO X DEFORMAÇÃO DE SOLOS RESIDUAIS NO EQUIPAMENTO TRIAXIAL
The knowledge of the mechanical behaviour of residual soils is of great importance in geotechnical projects, because of its abundance in tropical regions, such as Brazil and particularly in the area of Rio de Janeiro. The present work presents a study on the fundamental stress-strain behaviour of a residual soil resulting from a profile of a gneiss rock in R

4. CUBICAL TRIAXIAL TESTS IN SATURATED SAND / ENSAIOS TRIAXIAIS CÚBICOS EM AREIAS SATURADAS
The subject of this dissertation is a detailed experimental study of the stress-strain-strength behavior of saturated sand under three-dimensional loading condition.The investigation was carried out in a cubic triaxial and a conventional apparatuses. The cubic triaxial apparatus has the advantage of independently controlling the magnitude of the three princi
