1. DURABILITY OF HDPE GEOMEMBRANES: AN OVERVIEW
The polymer demand for geotechnical applications has been growing. The geomembrane is a geosynthetic, manufactured, polymeric product and is often specified in environmental projects. Geomembranes started to be used in the 1930s but became more widespread in the 1940s. In the 1970s, geomembranes began to be specified for landfills. Over the past forty years,

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. Physical stability of iron ore caves: geomechanical studies of a shallow underground cave in SE Brazil
Abstract Caves hosted in iron formations are attracting considerable interest due to their scientific and environmental value. Some of these caves are located in or near iron ore mine sites, which represent an important source of income to Brazil. However, the Brazilian legislation requires speleological studies that currently have an impact upon ore reserve

5. 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

6. 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

7. Banco de dados geológico-geotécnicos com base em sondagens à percussão e uso de SIG: análise espacial da profundidade do lençol freático e do \ N IND.SPT\ para obras de fundação em João Pessoa - PB / Geological-geotechnical Database with SPT sounding data and GIS: spatial analysis of water table level and \ N IND.SPT\ values applied to foundation maps in João Pessoa - PB (Brazil)
Geological-geotechnical databases have been used as important assistant tools in urban and environmental management activities. However, the kind of information necessary for one to work with such tools may not always be available or easily supplied. This work concerns the generation of a Decision Support System undertaken through means of a Geographic Infor

8. GESTÃO DE RISCOS E PLANO DE AÇÕES EMERGENCIAIS APLICADO À BARRAGEM DE CONTENÇÃO DE REJEITOS CASA DE PEDRA/CSN
Mineral production in Brazil has been greatly increased in recent years, particularly in the region of the province of mineral Quadrilátero Ferrífero, which has required on the part of mining companies, adopting policies to control and monitoring of their tailings disposal systems. Recent breakthroughs of these structures have mobilized considerable concer

9. 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

10. 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

11. GEOWEB, um facilitador para a aprendizagem em geotecnia / GEOWEB, a facilitator for learning in geotechnical
Historically and with more emphasis on the international level, efforts have been dedicated in the design and implementation of Learning Objects for the teaching of soil mechanics courses in Civil Engineering, in particular, to the topic of Water Movement in Soil. Following this vision, this paper examines the relationship between teaching and learning in th
