  • A new column collapse apparatus for the characterisation of the flowability of granular materials 

    Torres Serra, Joel; Romero Morales, Enrique Edgar; Rodríguez Ferran, Antonio (2020-02)
    Article
    Restricted access - publisher's policy
    The packaging industry is lacking a standard methodology to characterise the granular flow of a wide range of powders and grains in actual handling conditions. We present a new fully-instrumented granular column collapse ...
  • Compacted soil behaviour: initial state, structure and constitutive modelling 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè; Gens Solé, Antonio (Thomas Telford, 2013-05)
    Article
    Open Access
    The paper explores the behaviour of compacted soils throughout the (dry density–water content) compaction plane by means of a conceptual framework that incorporates microstructural information. The engineering properties ...
  • Criteria for rapid sliding I.: a review of Vaiont case 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (2010-08)
    Article
    Open Access
    Vaiont slide has been represented by a model of two interacting evolutive wedges. Mass conservation during the motion implies that the upper wedge transfers mass to the lower one through an internal shearing plane. The ...
  • Criteria for rapid sliding II.: thermo-hydro-mechanical and scale effects in Vaiont case 

    Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (2010-08)
    Article
    Open Access
    Thermally induced excess pore pressures have been included into a two-wedge evolutive model of Vaiont landslide. The problem requires the solution of a system of four coupled balance equations for the shear bands and the ...
  • Canelles landslide: modelling rapid drawdown and fast potential sliding 

    Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo; Corominas Dulcet, Jordi; Moya Sánchez, José (2012-03)
    Article
    Open Access
    A large landslide (40 × 106 m3) was reactivated on the left bank of Canelles reservoir, Spain. The instability was made evident after a considerable reduction of the reservoir level. The drawdown took place during the ...
  • Characterisation of the multi-scale fabric features of high plasticity clays 

    Cotecchia, Federica; Guglielmi, S.; Cafaro, F.; Gens Solé, Antonio (Institution of Civil Engineers (ICE), 2019-12)
    Article
    Restricted access - publisher's policy
    An investigation of the microstructural features of a high-plasticity clay, in both its natural conditions and reconstituted in the laboratory, is described. Scanning electron microscopy is used here to characterise the ...
  • Landslide motion assessment including rate effects and thermal interactions: revisiting the Canelles landslide 

    Alvarado Bueno, Mauricio; Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (2019-09)
    Article
    Open Access
    The re-activation of a large (40 Mm3) landslide on the valley slopes of a reservoir motivated a research initiative to estimate the risk of a fast-sliding mass moving into the reservoir. A previous simplified analysis had ...
  • Physical evolution of a bentonite buffer during 18 years of heating and hydration 

    Villar Galicia, María Victoria; Iglesias, Rubén Javier; Garcia Siñeriz, Jose Luis; Lloret Morancho, Antonio; Huertas Ilera Ilera, Fernando (2020-01)
    Article
    Restricted access - publisher's policy
    The FEBEX in situ experiment was a full-scale test reproducing the near-field of an underground nuclear waste repository. It was performed in a gallery excavated in granite, two heaters simulated the thermal effect of the ...
  • Micromechanical inspection of incremental behaviour of crushable soils 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; O'Sullivan, Catherine; Gens Solé, Antonio (Springer, 2019-10)
    Article
    Open Access
    In granular soils grain crushing reduces dilatancy and stress obliquity enhances crushability. These are well-supported specimen-scale experimental observations. In principle, those observations should reflect some peculiar ...
  • Thermo-hydro-mechanical coupled modeling of methane hydrate-bearing sediments: formulation and application 

    de la Fuente Ruiz, María; Vaunat, Jean; Marín Moreno, Héctor (2019-06)
    Article
    Open Access
    We present a fully coupled thermo-hydro-mechanical formulation for the simulation of sediment deformation, fluid and heat transport and fluid/solid phase transformations occurring in methane hydrate geological systems. We ...
  • A stable mesh-independent approach for numerical modelling of structured soils at large strains 

    Monforte Vila, Lluís; Ciantia, Matteo Oryem; Carbonell Puigbó, Josep Maria; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (Elsevier, 2019-12)
    Article
    Restricted access - publisher's policy
    We describe the large strain implementation of an elasto-plastic model for structured soils into G-PFEM, a code developed for geotechnical simulations using the Particle Finite Element Method. The constitutive model is ...
  • Induced seismicity in geologic carbon storage 

    Vilarrasa Riaño, Víctor; Carrera Ramírez, Jesús; Olivella Pastallé, Sebastià; Rutqvist, Jonny; Laloui, Lyesse (2019-06)
    Article
    Open Access
    Geologic carbon storage, as well as other geo-energy applications, such as geothermal energy, seasonal natural gas storage and subsurface energy storage imply fluid injection and/or extraction that causes changes in rock ...
