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. 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

3. Characterization of Sobradinho landslide in fluvial valley using MASW and ERT methods
Abstract Landslides can substantially impact the fluvial systems, which is why the continuous mapping of their extent, evolution and stability assessment is crucial. However, in such environments, material identification (e.g. colluvium) and subsurface characterization by the methods used for geologic mapping and geotechnical investigation is often a challen

4. Field compaction control by way of correlation between elasticity module and layer rigidity with moisture content
Abstract The present research had as its basic objective to contribute with the improvement in the quality control evaluation of the compacting process in road works. The real contribution of the survey is to establish an innovative way of controlling the compaction process in the field, with employment of the Humidity versus Rigidity and the Humidity versus

5. 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

7. 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

8. ESTUDO DA ERODIBILIDADE DE SOLOS E ROCHAS DE UMA VOÇOROCA EM SÃO VALENTIM, RS / STUDY OF SOIL AND ROCK ERODIBILITY IN A GULLY IN SÃO VALENTIM, RS
A pesquisa, da qual resulta esta dissertação de mestrado, se desenvolveu em uma voçoroca, conhecida como Buraco Fundo localizada no município de Santa Maria/RS. O objetivo principal foi o estudo da erodibilidade dos solos superficiais (horizonte A/B) e do substrato rochoso (rocha alterada, siltito e arenito) de um perfil típico da área da voçoroca. A

9. 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
