1. Shear strength of an unsaturated soil with direct measurement of suction / Resistência ao cisalhamento de um solo não saturado com medida direta de sucção
The purpose this study was to measure the suction with high capacity tensiometer (HCT), placed at the bottom of the sample, during shear strength tests on a compacted soil. Three kinds of shear strength tests were performed on the sample in different conditions of saturation: triaxial consolidated drained in saturated condition, triaxial consolidated undrain

2. "Estudo do comportamento de um solo residual de gnaisse não saturado para avaliar a influência da infiltração na estabilidade de taludes" / "Study of the behavior of a residual unsatured soil for evaluated of the influence infiltration in the slope stability"
Landslides in tropical soils are often the result of advance of the wetting due to rainfall. This advance results from an increase in pore water pressure, reduction in present soil matric suction, reduction in the shear strength of the soil. This work will present a study related to the shear strength of unsaturated soils, including an experimental study, in

3. Estudo sobre a resistência ao cisalhamento de um solo residual compactado não saturado. / Study on the shear strength of a residual unsaturated soil.
The main focus of this study is to investigate some aspects of the shear strength and water retention properties of a compacted residual soil, under unsaturated condition. A residual of gneiss obtained from the geotechnical experimental site of the University of São Paulo was used. Based on the compaction curve three molding conditions were adopted for the
