This paper presents the results of numerical investigations on the deformation behaviour of a tunnel face reinforced by longitudinal pipes. The three dimensional finite difference calculations are based on series of reduced-scale centrifuge model tests (Al Hallak, 1999). Numerical analyses are developed and carried out with particular emphasis on the va...
View ArticleMunicipal solid waste landfill is a potential source of contamination due to the harmful elements of the leachate, such as trace elements. In the Belo Horizonte landfill, the waste is partially disposed of directly on gneiss saprolites, with lower capacity to mitigate contaminants than upper soil horizons. Column tests were made to analyse the attenuati...
View ArticleThis paper describes a mechanical device to compare the energy transference from the blow of a hammer to the stem referring to standardized and non-standardized equipment in Brazil. The device allows to measure the vertical displacement of a sleeve due to one or more blows of a hammer falling freely. Tests were carried out using three pieces of equipmen...
View ArticleIn the case of rock-fluids interaction, numerous studies have mainly focused on field and numerical simulations regarding the existence of toxic gases and investigations about the possibility of gas burst. This paper is related to the development of experimental investigations for granite formations on samples obtained from Creighton mine, Sudbury, Cana...
