Drained and Undrained Behavior of an Aeolian Sand from Natal, Brazil

March 11, 2020

The behavior of sands subjected to diverse loading conditions has been the object of many studies in recent decades. Constitutive models that are able to simulate the behavior of sands have been developed based on critical state theory. Researchers have shown that the defining parameters of the critical state line (CSL) can be obtained by performing dra...

Residual Shear Strength of a Residual Soil of Granulite

February 14, 2020

This paper discusses the residual shear strength of a granulite residual soil that was involved in a large landslide in Brazil. The residual strength was investigated because of the great mobility achieved by the soil after failure. The experimental program comprised physical and mineralogical characterization and residual shear strength measurements. D...

Effects of Hydraulic Gradient Variation on the Structure and Strength of a Compacted Tropical Soil

May 26, 2020
Tropical soils have been extensively studied to evaluate the technical feasibility of their application in hydraulic earthworks such as compacted clay barriers in landfills. In these earthworks, the water flow in the porous medium generates percolation forces that can promote structural changes in the soil, with possible deleterious repercussions on its mechanic...

Mapping of Geological-Geotechnical Risk of Mass Movement in an Urban Area in Rio Piracicaba, MG, Brazil

November 06, 2019
The objective of this study is to create a geological-geotechnical risk map of mass movement for an urban perimeter of Rio Piracicaba city, state of Minas Gerais, MG, Brazil, by applying the methodology proposed by the Brazilian Ministry of Cities. Four neighborhoods were evaluated through works conducted in the field and with the aid of a GIS fed with aerial im...
