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. 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

3. Geological - geotechnical characterization of different lithotypes in an underground mine
Abstract A mineralogical, geological and geotechnical characterization of several rock types (phyllite, dolomite, breccia and marl) from an underground mine site aimed, among other things, to identify its mineral composition and to provide parameters to support the understanding of rock mass behavior. For this purpose, it was possible to perform laboratory a

4. 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

5. Stabilization of sandy soil with high content of asphalt emulsion
Abstract The purpose of this article is to evaluate the shear strength parameters of mixtures of sandy soil with high asphalt emulsion contents for their use in geotechnical structures, such as zoned earth dams, embankments, etc. The methodology adopted consisted of: collecting and characterizing samples of sandy soil to be laboratory tested; compacting the

6. Assessment of the effects of vegetational cover on the long-term stabilityof a waste rock dump
Abstract Waste rock dump reclamation includes re-grading the banks to flatten the overall slope followed by re-vegetation. These measures are required to reduce surface erosion, provide physical stability, and meet future use goals. In some cases, the presence of trees can cause localized shear zones in a waste rock dump by the load of the tree mass and the

7. 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

8. Soil Stabilization with Lime for the Construction of Forest Roads
ABSTRACT The mechanical performance of soil stabilization using lime to improve forest roads was assessed. This study was conducted with lateritic soil (LVAd30) using lime content of 2% in the municipality of Niquelândia, Goiás state, Brazil. Geotechnical tests of soil characterization, compaction, and mechanical strength were performed applying different

9. 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

10. 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

11. 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
