Resumo:
The present research work had two main objectives. The first was to obtain a geotechnical index for measuring the weathering degree of gneissic residual soils. For that it were analyzed data corresponding to typical weathering profiles found in the municipality of Rio de Janeiro and executed a complete characterization of a specific weathering profile of facoidal gneiss. The second objective was to determine, experimentally, the hydraulic properties of tropical unsaturated soils. As part of that new instruments were developed and existing equipments were modified. Moisture retention curves were determined for six residual soils and two sedimentary ones. The axis- translation technique, the filter paper method and the relative humidity one were employed to obtain such curves. Data from mercury intrusion porosimetry tests were also used to define these curves. The applicability of models available in literature to adjust the obtained experimental data was evaluated. The hydraulic conductivity function was determined for two soils, one residual and one sedimentary. A suction controlled, flexible wall permeameter set up was used for that. Numerical modeling was implemented to evaluate the performance of the experimental set up. This provided means for an optimized interpretation of the testing results. The applicability of models available in the literature to obtain the permeability functions was evaluated, being found the need to introduce changes in their formulation in order to be able to reproduce the obtained experimental data.
