This paper describes the behaviour of a 10 m high trial embankment built on silt gold mine tailings of Morro do Ouro Dam, Brazil. The dam is the country’s largest tailings dam having 120 m in height and 4 km in length. This trial aimed at investigating tailings strength behaviour, which field experience has already indicated to be better than ...
View ArticleTailings dams constructed using the upstream method generally have relatively low- density materials with a high degree of saturation. Such conditions can generate the phenomena of liquefaction, which is potentially critical in
slurry tailings disposal systems. Slope stability analyses involving liquefied soil require that the shear resistan...
This paper presents a new method for predicting the axial capacity of piles from dynamic penetration tests which is based on the concepts of soil dynamics and principles of energy conservation. The energy delivered to the hammerrod-sampler system and transferred to the soil is computed from the numbers of blow counts Nspt and is a...
View ArticleThis paper presents the results from a preliminary inventory of natural and man-made hazards and/or disasters in Brazil. The data were collected from previous studies, aerial photographs, satellite images and field studies. The data were obtained to evaluate the spatial distribution of natural and man-made hazards and disasters in different cities and s...
