The occurrence of a 5.9 magnitude earthquake, in February 2007, that affected two rockfill dams in Portugal, led to a study presented in this paper about the structural performance of rockfill dams under earthquake influence. Taking into account the world knowledge it can be concluded that the dynamic actions have mainly produced some displacements, and...
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 ArticleSoil water retention curve (SWRC) plays a fundamental role in characterizing hydraulic and mechanical behavior of soils and porous material in general. However, the determination of the SWRC is usually time-consuming. The objective of this paper is to describe a procedure for the determination of the SWRC using a high capacity tensiometer (HCT). The pro...
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...
