The topographic and geological conditions of several regions in Brazil favour the formation of large deposits of soft soils. Sometimes this requires the use of innovative techniques to allow constructions of geotechnical works in these sites. The presence of deep soft foundation soils has led to an increasing number of reinforced bridge abutments being ...
View ArticleThis paper describes the results of research carried out for evaluating the effects of hydrated lime, with and without chemical activators, for the modification (up to 2% lime) and stabilisation (more than 2% lime) of residual granite soils. The effects of the modification of granitic soils with the addition of 2% calcitic lime were studied; and the res...
View ArticleThe authors are to be congratulated for presenting a paper with a significant amount of data on soft soils. The kind of data presented is of great value for geotechnical engineering practice, particularly for those involved with soft soils. To facilitate the discussion´s follow-up, the discus-sers have used the same items that have been used by the aut...
View ArticleAlthough expansive soils have been widely studied by different authors, just a few have made methodological proposals to comprehensively evaluate this phenomenon. The aim of this paper is to suggest a methodology which will serve as guideline to evaluate soil expansiveness in a... View Article
