In this study, a particle-based approach is employed to simulate the fluid flow through single fractures considering detailed geometrical characteristics of the fracture walls at meso-scale. For this purpose, Lattice Boltzmann Method (LBM) which is an efficient computational fluid dynamic method for simulation of fluid flow in media with grossly irregul...
View ArticleMass 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 ArticleSouth Americas topographic characteristics and available materials have led engineers to select earth or rockfill material for dams construction. However, there are tropical regions with high annual rainfall where the soil compaction above the optimum moisture must be studied in detail. This research presents the results of tests performed on compacted ...
