A methodology to obtain the block size distribution of a large rockfall deposit
(2014)
Conference lecture
Restricted access - publisher's policyThe block size distribution produced in a rockfall event is necessary for the study of the trajectories, run-out, the impact energies and for the quantitative assessment of the rockfall hazard. For large rockfall deposits, ... -
A study of the effects of suction and roughness on the mechanical behaviour of rock joints
(2011)
Conference report
Restricted access - publisher's policyThe experimental investigation focused on the effects of suction on the mechanical behaviour of rock joints. Available experimental data on the effect of moisture on joint behaviour is very scarce. Laboratory tests were ... -
A textural classification of argillaceous rocks and their durability
(2015-08)
Article
Open AccessArgillaceous rocks can display a wide range of durability behavior after excavation and in cut slopes. In this paper, we propose a classification of argillaceous rocks based on their textural characteristics. Three main ... -

Open AccessEl artículo presenta una formulación probabilística del problema del análisis retrospectivo, basado en un criterio de máxima verosimilitud. La formulación está organizada de forma jerárquica, de manera que se pueden ... -
Análisis simplificado de la mecánica de impacto de bloques rocosos sobre sustrato rígido y su aplicación a casos de ensayos de lanzamiento
(Universitat Politècnica de Catalunya, 2018-09-28)
Master thesis
Open Access
Covenantee: Geomar Enginyeria del TerrenyLos bloques desprendidos de paredes rocosas suelen fragmentarse al colisionar con un sustrato rígido. Experiencias previas de ensayos de lanzamiento de bloques sugieren que la geometría del impacto puede jugar un papel muy ... -
Application of zero-thickness interface elements to sanding prediction analysis
(2020-07)
Article
Restricted access - publisher's policyA computational micromechanical analysis based on zero thickness interface elements for modelling solid prediction in hydrocarbon reservoir sandstones is presented. The model is capable of modelling localization of ... -

Open AccessAquest estudi analitza la problemàtica que genera la reconversió d’una pedrera en un abocador de residus especial, concretament als peus de Collserola en els terrenys que ara ocupa la pedrera de Mina Berta situada al Vallès ... -
Changes in hydrodynamic, structural and geochemical properties in carbonate rock samples due to reactive transport
(Elsevier, 2017-01)
Article
Open AccessReactive transport plays an important role in the development of a wide range of both anthropic and natural processes affecting geological media. To predict the consequences of reactive transport processes on structural ... -
Comparing kinematically detachable rock masses and rockfall scar volumes
(Institute of Physics (IOP), 2015)
Conference report
Open AccessIn rockfall prone areas the evaluation of the risk due to worst case scenarios requires the establishment of maximum thresholds for the expected rockfall volumes. The magnitude of such instabilities is often related to ... -
Comparison of block size distribution in rockfalls
(2015)
Conference lecture
Restricted access - publisher's policyRock masses detached as rockfalls usually disintegrate upon impact on the ground surface. The knowledge of the Rockfall Block Size Distribution (RBSD) generated by the propagation of the rockfall mass is required for th e ... -
