1. Rheology of mine tailings deposits for dam break analyses
Abstract This article deals with the rheology of tailings deposits related to dam break analysis. The material used was a fine tailings from iron ore processing. Geotechnical and rheological characterization of these tailings were performed. The rheological characterization consisted of rotational and oscillatory tests. It was observed that the rheological p

2. 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

3. 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

4. Rheology applied to the environmental management of mineral tailings: focus on safer disposal and water reuse
Abstract Mining activities worldwide are subject to serious geotechnical accidents involving tailings dams. Therefore, many studies have focused on tailings dewatering before their deposition. This article studies the rheological properties of flocculated and thickened nickel tailings in order to determine the effect of the initial solid concentration and ty

5. Use of convolution and geotechnical rock properties to analyze free flowing discharge test
Testes de bombeamento são realizados para determinar a transmissividade (T) e coeficiente de armazenamento (S) do aquífero. No entanto, a interpretação dos dados do teste não é única e os resultados podem variar, dependendo das hipóteses adotadas. Neste trabalho, a técnica de convolução é aplicada para a reconstrução de curvas de rebaixamento o

6. Caracterização de rejeitos de minério de ferro para uso em pavimentação / Characterization of iron ore tailings for use in paving
In this work it was carried out a series of laboratory tests towards chemical, mineralogical and geotechnical characterization of rejects from iron ore processing, for use in paving. Material sampling was done in specific points as they were generated during the beneficiation process along the cycle, in order to preserve their properties. The alternative app

7. Estudo da interação de paredes de alvenaria estrutural com a estrutura de fundação
This dissertation presents a study of factors that influence the soil-structure interaction mechanism in buildings and their implications on the behavior of them. Firstly, an extensive bibliographical review was made, and this study broached the main concepts of the SSI research field, such as constitutive models of soil, discrete models to represent soil, s

8. tropical soils, bentonite, hydraulic conductivity, compatibility, barriers. / CONDUTIVIDADE HIDRÁULICA E COMPATIBILIDADE EM COMBINAÇÕES DE SOLO TROPICAL E BENTONITA PARA USO EM BARREIRAS
Barriers are key elements for the environmental protection in waste disposal sites. Additionally, compacted tropical soils have great potential to be used in these barriers, once some technical matters are correctly addressed, including low hydraulic conductivity and adequate compatibility to the disposed fluids. In this context, the bentonite addition in tr

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.

11. GCL shear strength evaluation - a new test method / Avaliação da resistência ao cisalhamento em GCLs - uma nova metodologia de ensaio
GCLs (Geosynthetic Clay Liners) are geosynthetic products used to compose flux control barriers in geotechnical and environmental works. The mechanical properties of GCLs have to be investigated in short and long term. Among its mechanical parameters, GCL internal shear strength plays an important role in the stability of slopes of geotechnical works. The ma

12. Análise do comportamento de estacas strauss submetidas a carregamento horizontal no solo da região de Londrina - PR
In Londrina city, Strauss piles are frequently used as retaining structure for building basement excavation, being submitted to horizontal load. However, the projects of such retaining structures are usually conducted using design methods that do not take the concrete cracking of pile transversal section and the properties of lateritic tropical soil into acc
