This paper illustrates the use of the seismic dilatometer (SDMT) to assess the decay of in-situ stiffness with strain level in different soil types. The approach adopted in this study relies on the ability of the SDMT to provide routinelyat each test depth both a small strain stiffness (G0...
View ArticleCone penetration in mixed or intermediate soils (soils containing mixtures of sand, silt and clay) is neither fully drained nor fully undrained at the standard cone penetration rate of 20 mm/s. Considerable research, mainly relying on centrifuge tests, has been undertaken to quantify the effects of penetration rate (and thus partial drainage) on cone re...
View ArticleThis paper presents results of the instrumentation of 373 blows from two SPT deployments performed in the Sarapuí II Test Site, located in Duque de Caxias, Rio de Janeiro. In these blows the hammer drop height, its velocity at impact, the rate of blows and also the energy transferred to the rod stem have been measured. It is therefor...
View ArticleComprehensive research has been carried out by the Geotechnical Group (GEGEP) of the Federal University of Pernambuco in the soft clay deposits in Northeastern Brazil near the city of Recife. This paper presents the results of important geotechnical investigations of soft clays in two areas within the Suape Port and Industrial Complex. The geotechnical ...
