In the Central Area of Brazil, particularly in the city of Goiânia (and in limited cases of the Brazilian capital Brasília), it is becoming common to observe in few foundation projects the design of a single, thick and large raft, supported by several piles, particularly for the central highly loaded and slender part of very tall bu...
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...
