Currently, most studies on stability of underground excavations include two separate analyses: the elastoplastic behavior of rock masses and/or kinematic analysis of possible wedges and blocks formed in the excavation walls. This paper presents a case study carried out at the Vazante Zinc Mine in Minas Gerais, Brazil, where studies on stability of under...
View ArticleThis article presents the geotechnical parameters from a laboratory investigation of a Quaternary sedimentary deposit located in a low-lying area of Macaé, Rio de Janeiro (RJ), Brazil, and, when possible, compares these parameters with those from field tests and other Brazilian studies on soft soils. The deposit is described in terms of its g...
View ArticleDuring routine inspection works in 2006 inspectors found resurgences of water at the toe of a small embankment dam named ″Ribeirão do Gama″, located at Brasília – DF. After technical visits, geotechnical engineers characterized these groundwater leakages as a piping process at an early stage. ...
