Geophysical methods are potent tools for geotechnical site characterization in a nondestructive way. They improve the extrapolation of punctual data from direct survey methods, allowing a fast and cost-effective evaluation of large areas. Ground Penetrating Radar (GPR) and DC electrical resistivity (ER) are the most requested methods for geotechnical an...
View ArticleThere are 15 papers published in this special issue of Soils and Rocks. The papers were selected among the best of 1165 papers presented in the Brazilian Conference of Soil Mechanics and Geotechnical Engineering (XX COBRAMSEG), Luso-Brazilian Congress of Geotechnics (XI CLBG) , Brazilian Symposium of Rock Mechanics (IX SBMR ) and Brazilian Symposium of ...
View ArticleEvery year, millions of tons of phosphogypsum, a by-product of the fertilizer industry, are produced worldwide. As just a small part of this amount is reused, this study analyzed a new alternative to reuse this material in geotechnical works, in mixtures with lateritic soil and bentonite for the construction of liners for sanitary landfills. Four compos...
View ArticleThis paper focuses on the use of the agglomerate technique to simulate crushable particles in the Discrete Element Method. A novel approach is proposed to design a Weibullian agglomerate by mimicking flaws within the crushable particle. The particle is designed with a constant number of sub-spheres in contrast to the approach widely used in the literatu...
