1. Obtaining geotechnical parameters from correlations between geophysics and CPT tests in tailings dams
Abstract This article introduces a hassle-free methodology for geotechnical parameters to be obtained from correlations between geophysics and CPT field tests in tailings dams undergoing the decommissioning process, which are reasonably representative of site conditions, from the very early project stages, with extensive coverage of all impoundment parts, wi

2. DIAGNÓSTICO AMBIENTAL DO MEIO FÍSICO DO CAMPO DE INSTRUÇÃO DE SANTA MARIA (CISM) / ENVIRONMENTAL DIAGNOSIS OF THE PHYSICAL ENVIROMENT AT CAMPO DE INSTRUÇÃO DE SANTA MARIA (CISM)
The Campo de Instrução de Santa Maria (CISM) is a military training area for armored troops. Such practices have caused environmental impacts related to the destruction of vegetation, erosion, and siltation of waterways. Since there is no environmental data for the area, the following research aimed to develop an environmental diagnosis of the physical env

3. Colapsibilidade com sucção controlada de um solo coluvionar e laterítico de Campinas/SP / Collapsibility with controlled suction of a colluvial and lateritic soil from Campinas/SP
This study aims at investigating the collapsibility of coluvionar and lateritic soil by oedometer tests with controlled suction, performed in the laboratory, and by the interpretation of the soilimpregnated thin plates before and after the tests, so as to take into account the differences between natural and "after collapse" structures. The undisturbed soil

4. Desenvolvimento de equipamento para realização de ensaios HCT com o uso da bomba de fluxo
In general, the tailings are disposed in the form of pulp, mainly because the condition of the residue is the natural byproduct of the minerals concentrations activities, always associated with large water demands. The final disposal of wastes in pulp occurs by hydraulic filling techniques in large reservoirs of check dams. In the case of more granular taili

5. Estudo em laboratório e em campo de colunas granulares encamisadas com geossintéticos
The construction of embankments on soft soils is a common challenge to be faced by geotechnical engineers. Several techniques have been developed to improve the performance of such works and the use of geosynthetics for the stabilisation of the soft soil or embankment reinforcement has been increasingly employed. The use of granular columns is also a traditi

6. Uso das técnicas HCT e TDR no monitoramento do proceso de consolidação em reservatórios de barragens de rejeitos / Monitoring of consolidation process in deposits of tailings dam by TDR and HCT techniques
The mining industry generates a large amount of tailing, which is usually placed in tailing dams. To properly design these constructions, when the tailing is highly compressible, it is necessary to study the consolidation characteristics of this material by means of techniques that consider large deformations. This study aimed to establish the technique HCT

7. 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.

8. Interação solo-estrutura em edifícios com fundação profunda: método numérico e resultados observados no campo / Soil-structure interaction in buildings with deep foundation: numerical method and results observed in field
Design of concrete structures for multi-story buildings with deep foundation is considered in this work, taking in account the soil-structure interaction. This interaction is analysed with a numerical method where the superstructure (slabs, beams, and columns), and the foundation structural elements (blocks and piles) are considered a unique structure, model

9. Ensaios dilatométricos - DMT em solos de Santa Catarina: estudo comparativo com CPT e SPT
The world-wide demand for the accomplishment of geotechnical in situ tests is increasing. With th rigorously indicated by the designers for a subsoil identification. The testing method Marchetti Dilatometer (DMT) has being widely used in the world, with different purposes. In this pioneering work with the DMT in Santa Catarina, comparisons between (Standard

10. Estudo das propriedades geotécnicas de solos residuais não saturados de Ubatuba (SP). / Study of the geotechnical properties of unsaturated residual soils of Ubatuba (SP).
This doctoral thesis focusing on the study of the geotechnical properties of unsaturated residual soils occurring in the municipal district of Ubatuba, north coast of the State of Sao Paulo. The study of geotechnical properties was conducted from a macro and micromorfology approach, seeking to establish the relationship between the water present in the resid

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
