1. Proposal of a failure envelope for artificially cemented sand
Abstract Soils are particulate materials, which often stand out for their low shear strength. In most cases, this aspect justifies adapting the geotechnical project for this characteristic, which can be even more problematic in the case of soft sands, since it often occurs in superficial layers in various parts of the metropolitan region of Fortaleza. Theref

2. Shear Strength of a typical soil from Manaus, Brazil, stabilized with ceramic residue additive
ABSTRACT The purpose of this study is to determine the geotechnical behavior of a clayey surface soil typical to the Manaus region (Amazonas, Brazil), when mixed with ceramic powder from brick residue produced by potteries located in the county of Iranduba, Amazonas, Brazil, and with residual sand (the reference mixture), commonly used in pavements in the re

3. Comportamento mecânico de solo argiloso estabilizado com resíduo de vidro pulverizado em moinho de alta energia e de bolas
RESUMO A capital do Estado Amazonas apresenta dificuldades na construção de pavimentos devido à predominância superficial de argila em seu perfil geotécnico. Tal material mostra-se inadequado para a construção de subcamadas dessas estruturas urbanas. Avaliou-se, no presente estudo, o comportamento mecânico do solo argiloso típico de Manaus-AM na sua

4. The Effect of Roots on the Shear Strength of Texturally Distinct Soils
ABSTRACT The aim of this work was to evaluate the roots influence on the shear strength of a clay soil and a sandy soil. Soil samples with and without roots were collected from experimental plantations of Atlantic Forest native species. The soil samples were then physically characterized and their shear strength tested in a laboratory. The results indicated

5. Influência de variáveis de compactação na estrutura dos solos: caracterizações geotécnica, química, mineralógica e microestrutural / Influence of laboratory compaction variables in soils structure: geotechnical, chemical, mineralogical and microstructural characterizations
This research addressed the effect of laboratory methods of static and dynamic compaction on compaction parameters, mechanical strength and compressibility of three gneiss residual soils (two young and one mature soils) and two granite residual soils (one young and one mature soils) from the Minas Gerais State, Brazil. Disturbed soils samples were collected,

6. Influência das propriedades físico-mecânicas e hídricas do solo na susceptibilidade a escorregamentos em vertente declivosa na Serra do Mar em Ubatuba, São Paulo / Influence of physical and mechanical properties of soil an hydro in susceptibility to landslides on steep slopes in the Serra do Mar, Ubatuba
The mass movements are natural phenomena of evolution of the slopes, but they cause great damage when being considered as a risk in one area if they have a vulnerability in the slope associated with human occupation or industry that brings risk population. The study area is located on the northern coast of São Paulo, Brazil. In the region of Serra do Mar, a

7. 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

8. RELAÇÃO ENTRE A EROSÃO MARGINAL, ATRIBUTOS FÍSICOS DO SOLO E VARIÁVEIS HIDROLÓGICAS E CLIMÁTICAS NO BAIXO SÃO FRANCISCO SERGIPANO / RELATIONSHIP BETWEEN RIVERBANK EROSION, SOIL PHYSICAL CHARACTERISTICS AND HYDROLOGICAL AND CLIMATIC VARIABLES IN LOWER SÃO FRANCISCO RIVER.
Em conseqüência da implantação de grandes projetos hidrelétricos no canal do rio São Francisco, a alteração do regime hídrico no seu baixo curso, tem provocado um avançado processo erosivo em função da vulnerabilidade do solo do talude da margem do rio e do caráter amplificado que algumas variáveis climáticas e hidrológicas. A consequência d

9. Geotechnical site characterization and study of an erosion process caused by urban setting / Investigação geotécnica e estudo de um processo erosivo causado por ocupação urbana
This dissertation presents geotechnical site characterization results of an erosion process area, in Bauru city, inland of São Paulo State, Brazil. The objective is to characterize the local soil and define the major causing factors for the erosion process evolution, which initiated with deforestation, soil sealing and discharge of pluvial and sewer water.

10. Braquiaria under irrigation in rotational grazing system and soil physical quality / IrrigaÃÃo em braquiÃria sob pastejo rotacionado e qualidade fÃsica do solo
The seasonality of forage production is a phenomenon of great importance because it is related to the indices of yield and profitability of livestock production. From that results the constant search for new forages and alternatives compatible with the several systems of production as well as the application of new technologies as pasture irrigation and fert

12. Back analysis the landslides in residual soils unsaturated / Retroanálise de escorregamentos em solos residuais não saturados
Five historical cases of landslides in the city of Salvador, Bahia, were studied through the survey and treatment of the preexistent data. Complementary experiments were accomplished through the instrumentation field using tensiometers and laboratory testing. The back-analysis, main objective of this research, was accomplished through the geometries of each
