Sample quality has a direct influence on the results of geo-mechanical parameters obtained in laboratory and in situ tests, potentially causing serious technical and economic consequences. In the study of soft soil behavior using laboratory tests, it is important to evaluate, and be able to quantify sample quality, and if necessary and possible, to corr...
View ArticleSeveral methods for prediction of the load-settlement curves of shallow foundations have been proposed based on in-situ testing data. However, the good accuracy of such prediction depends on the definition of appropriate soil stiffness. Seasonal variability and its influence on the soil behavior need to be considered for unsaturated tropical soils. In t...
View ArticleIn this study, numerical modeling is used to evaluate the performance of rigid inclusion foundations for settlement control considering the characteristic soils of the city of BrasÃlia, Federal District, Brazil. Two- and three-dimensional (2D and 3D) PLAXIS software models were used considering the Hardening Soil constitutive model p...
View ArticleMicrostructural parameter assessment of reservoir rocks is extremely important for oil companies. In this regard, computerized X-ray microtomography (μ-CT) has proven to be an exceptionally useful methodology for the analysis of these rocks, since it provides significant microstructural parameters, such as porosity, permeability, and pore distrib...
