Results of triaxial tests performed in saturated and unsaturated compacted soil specimens with different interstitial fluids are presented. Tests were carried out in order to study the influence of the fluid relative dielectric constant, εr... View Article
Mass movements are one of the main causes of loss of people and environmental assets. Several factors contribute to mass movements, such as terrain morphology, rainfall regime, soil properties, land use and occupation. Studies showed that in the Northeast region of Brazil, between the years of 1991 and 2012, 38 events related to mass movements were reco...
View ArticleTo investigate the effect of particle size on mechanical properties of calcareous sand, a series of consolidated drained triaxial tests were performed on calcareous sand with different particle sizes. At a low effective confining pressure of 50 kPa, the shear peak strength increases with the increasing particle size. However, under a relatively large ef...
View ArticleThe Standard Penetration Test (SPT), widely used in Brazil, provides reference data to geotechnical projects. The data obtained are punctual and often dispersed due to its execution, that is, there is no concern in gathering and analyzing such information jointly for a specific region.... View Article
