    This paper presents the numerical analysis of an experimental soil drying test carried on an initially slurry soil specimen with controlled temperature and relative humidity in a laboratory environmental chamber. The imposed ...
  • Benchmark study of simulators for thermo-hydraulic modelling of low enthalpy geothermal processes 

    Mindel, Julian E.; Alt-Epping, Peter; Les Landes, Antoine Armandine; Beernink, Stijn; Birdsell, Daniel T.; Bloemendal, Martin; Hamm, Virginie; López, Simon; Maragna, Charles; Nielsen, Carsten M.; Olivella Pastallé, Sebastià; Perreaux, Marc; Saaltink, Maarten Willem; Saar, Martin O.; Van den Heuvel, Daniela; Vidal Montes, Rubén; Driesner, Thomas (2021-11)
    Article
    Open Access
    In order to assess the thermo-hydraulic modelling capabilities of various geothermal simulators, a comparative test suite was created, consisting of a set of cases designed with conditions relevant to the low-enthalpy range ...
  • Homogenización de barreras de arcilla para residuos nucleares 

    Gens Solé, Antonio; Barboza de Vasconcelos, Ramón; Rodríguez Romero, Carlos Eduardo; Vaunat, Jean; Villar Galicia, María Victoria (2021-07)
    Article
    Open Access
    Las funciones de seguridad de las barreras de bentonita para residuos nucleares dependen principalmente del valor de su densidad seca (o porosidad). La evolución de esta variable durante la fase transitoria de la barrera ...
  • Modelling methane hydrate saturation in pores: capillary inhibition effects 

    de la Fuente Ruiz, Maria; Vaunat, Jean; Marín Moreno, Hector (2021-09)
    Article
    Open Access
    Experimental and field observations evidence the effects of capillarity in narrow pores on inhibiting the thermodynamic stability of gas hydrates and controlling their saturation. Thus, precise estimates of the gas hydrate ...

    Tourchi, Saeed; Vaunat, Jean; Gens Solé, Antonio; Bumbieler, F.; Vu, Minh-Ngoc; Armand, G. (Elsevier, 2021-05)
    Article
    Restricted access - publisher's policy
    The paper describes the performance, observations and numerical interpretation of a full-scale in situ heating test conducted on Callovo-Oxfordian (COx) claystone in the Meuse / Haute-Marne (MHM) Underground Research ...
  • Effect of microstructure and relative humidity on strength and creep of gypsum 

    Ramon Tarragona, Anna; Caselle, Chiara; Bonetto, Sabrina Maria Rita; Costanzo, Daniele; Alonso Pérez de Agreda, Eduardo (2021-08)
    Article
    Open Access
    The wide range of gypsum facies observed all over the world and the strong heterogeneity that may be present even within a single facies often cause an inhomogeneous mechanical response that, if neglected, may be particularly ...
  • Analysis of cone penetration in brittle liquefiable soils 

    Monforte Vila, Lluís; Gens Solé, Antonio; Arroyo Alvarez de Toledo, Marcos; Mánica Malcom, Miguel Ángel; Carbonell Puigbó, Josep Maria (Elsevier, 2021-06)
    Article
    Restricted access - publisher's policy
    The paper presents a comprehensive set of simulations of the cone penetration test with pore pressure measurements (CPTu test) in brittle, potentially liquefiable, soils using advanced numerical techniques. The large ...
  • Analysis of the process of compaction movements of deposits of crushed salt tailings

  • Experimental analysis of desiccation cracks on a clayey silt from a large-scale test in natural conditions 

    Cordero Arias, Josbel Andreina; Prat Catalán, Pere; Ledesma Villalba, Alberto (2021-07)
    Article
    Restricted access - publisher's policy
    This paper presents an experimental investigation on the impact of environmental variables on soil cracking in natural conditions. The test was performed on a large soil specimen of initial size 3 × 3 × 0.5 m exposed to ...
  • A contact model for rough crushable sand 

    Zhang, Ningning; Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2021-06)
    Article
    Open Access
    Sand roughness is now accessible to measurement. Incorporating this parameter into sand models using the discrete element method (DEM) is known to improve bulk small strain response. In this work we explore the effect on ...
  • DEM examination of SPT correction factors 

    Zhang, Ningning; Arroyo Alvarez de Toledo, Marcos; Ciantia, Matteo Oryem; Gens Solé, Antonio (2021-06)
    Article
    Open Access
    The Standard Penetration Test (SPT) is the most widely used method for dynamic testing of soils. The test is simple and robust but difficult to control and not fully standardized. As a result, experimental results typically ...
