1. Resistência de um solo não saturado a partir de ensaios com teor de umidade constante (CW) / Shear strength of an unsaturated soil from constant water content tests
In many parts of the world, geotechnical engineers frequently deal with unsaturated soils, and the performance of constructions on such soils depends on their mechanical characteristics, and among them, the shear strength. The unsaturated soil shear strength can be experimentally determined by using techniques which allow soil suction control or measurement

2. Metologia para determinação de parâmetros para solos não saturados utilizando ensaios com umidade conhecida
In general the determination of constitutive parameters for unsaturated soils requires tests with controlled suction or allows measurement of suction. In this case it is highlighted the technique of axis translation, steam transfer or osmotic techniques. But generally most laboratories of soil mechanics do not have these tests and even when they are availabl

3. Study on factors which affect the accuracy of the filter-paper method. / Estudo sobre fatores que influenciam a acurácia do método do papel-filtro.
The purpose of this work is to verify the susceptibility of the filter-paper method to variations in three experimental parameters: roughness of porous medium (structure of porous matrix), period of exposition of the filter-paper to pore water (equilibration time) and degree of deficiency in contact between the filter-paper and the porous medium. In order to

4. Development of an equipament for the study of transport of automotives pollutants in unsaturated soils / Desenvolvimento de um equipamento para o estudo do transporte de poluentes automotivos em solos não saturados
This work had as main objective the development of an equipment for the experimental determination of the characteristic curve of suction, and the experimental determination of the effective permeability to unmixed fluids in multiphase systems (three phases), specifically gasoline, water and air, being focused the several properties involved in the multiphas
