The characteristics of the subgrade soil, obtained from laboratory and in situ tests, are of fundamental importance to the design of pavements. The tests carried out in the field, such as CBR in situ, Bredboard and others, represent more significantly the conditions of the soil. The Dynamic Cone Penetrometer (DC...
View ArticleThe general characteristics of granular soils reinforced with fibres have been reported in previous studies and have shown that fibre inclusion provides an increase in material strength and ductility and that the composite behaviour is governed by fibre content, as well as the mechanical and geometrical properties of the fibre. The present work presents...
View ArticleProbabilistic and deterministic stability analyses of the progress of a large mine pit excavation in Brazil are presented herein. A simple method of reliability analysis for quantifying the probability of failure of slopes has been considered and its advantages and limitations are briefly discussed. The variance of the factor of safety is computed for s...
View ArticleThis paper presents a program of direct shear tests in soil reinforced with geogrids, carried out with large-scale equipment. A woven geogrid was placed in sandy soil and positioned with different inclinations inside the shear box. The
strength parameters of the soil-geogrid interface were obtained from shear tests with the geogrid positione...
