A case study describing the experience in modeling and designing the process of construction of the Rio Grande
Breakwater on soft clay deposits is summarized in this paper. Field performance during and after embankment construction was monitored with inclinometers, magnetometers and electrical piezometers providing the necessary information ...
Steel pipe umbrellas have been used to tunnel in difficult conditions or in weak rock masses and/or soils. Despite
the large number of applications around the world, there are still some doubts concerning how pipe umbrellas behave under
loading when the tunnel face advances. For this reason, a scale laboratory model of pipe umbre...
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...
