1. Carbon and Nitrogen Stocks Under Different Land-Use in the Paraopeba River Basin-MG Before the Corrégo do Feijão Dam Burst
ABSTRACT Soil attributes can provide indicators for the management and conservation of natural and agrarian ecosystems. This study was carried out before the rupture of the Córrego do Feijão dam and aimed to evaluate and quantify the stocks of carbon, nitrogen and the C/N ratio in soils around the Paraopeba-MG river basin in five regions corresponding to t

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. Evaluation of Live Cuttings Effect on Slope Stability
ABSTRACT The aim of this work was to evaluate the development of shrub live cuttings and their effect on slope stability. Vertical in situ pullout tests and measurements of Phyllanthus sellowianus shoots and roots of 2, 4, 6, 8, 10 and 14 months old were conducted. Stability analyses were conducted for slopes with planar and curved rupture surfaces and for

4. Reference Values of Soil Quality for the Rio Doce Basin
ABSTRACT: The great geological and soil variation in the state of Minas Gerais, Brazil, indicates the need for regional studies to understand the geochemical background of soils. The Rio Doce Basin became a priority area for geochemical background determination after the rupture of the tailings dam of Fundão in 2015. In this context, the objectives of this

5. ANÁLISE DE TORRES DE LT CONSIDERANDO A INTERAÇÃO SOLO-ESTRUTURA / THE SOIL-STRUCTURE INTERACTION IN TRANSMISSION LINES LATTICED STEEL TOWERS ANALYSES
O modelo mecânico usualmente adotado no projeto de torres metálicas treliçadas é bastante simples, utilizando elementos de treliça e/ou pórtico espacial, e resolvido através de uma análise estática e linear ou não linear geométrica. Nas hipóteses de carga de ruptura de um cabo condutor ou um cabo pára-raios o carregamento é considerado através

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. Estudo da correlação entre resistência mecânica e velocidade ultrassônica para um material terroso
This dissertation presents the studies carried out on the applicability of ultrasound as a non-destructive evaluation method of the structural conditions of earth structures designed to building rammed earth. To this purpose the ultrasound was defined as a proposal for utilization of a non-destructive method on the evaluation of the relation of earthy materi

8. Evaluation of the mechanic behavior of fiber reinforcement in a fine sandy lateritic soil applies in pavement layers / Avaliação do comportamento mecânico de um solo arenoso fino laterítico reforçado com fibras para uso em pavimentação
The propose of this study is to evaluate the effect of the randomly distributed fiber reinforcement in the compression and tension resistances, deformability and resilient modulus of a fine sandy lateritic soil (FSLS) for base layer of pavements. Glass fibers and polypropylene fibers were studied. The first was added in contents of 0,5%, 1,0% and 1,5% with l

9. 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

10. APLICATIONS OF PROBABILITY AND STATISTICS IN GEOTECHNICAL ANALYSES / APLICAÇÕES DE PROBABILIDADE E ESTATÍSTICA EM ANÁLISES GEOTÉCNICAS
In geotechnical analyses, forecasts of safety factors or deformations are developed on the basis of deterministics methods, that admit as fixed and known the parameters of the soil or the rock. However, such forecasts are affected by uncertainties proceeding from the reproduction impossibility of the field conditions in laboratory, of the disturbance of the

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
