    • Fully coupled thermo-hydro-mechanical double-porosity formulation for unsaturated soils 

      Sánchez, Marcelo; Gens Solé, Antonio; Victoria Villar, María; Olivella Pastallé, Sebastià (2016-12)
      Article
      Accés obert
      This work presents a fully coupled formulation developed to handle engineering problems in unsaturated (and saturated) soils that present two dominant void levels. The proposed framework assumes the presence of two porous ...

    • Generalized plasticity for geomaterials with double structure 

      Gens Solé, Antonio; Sánchez, Marcelo; Valleján, Beatriz (CIMNE, 2011)
      Text en actes de congrés
      Accés obert
      The paper presents a double structure constitutive model based on a generalized plasticity formalism. The behaviour of macrostructure, microstructure and their interactions are described. A coupled hydromechanical formulation ...

    • Mechanical behavior of an unsaturated clayey silt: an experimental and constitutive modelling study 

      Romero Morales, Enrique Edgar; Sánchez, Marcelo; Gai, Xuerui; Barrera Bucio, Mauricio; Lloret Morancho, Antonio (2019-10)
      Article
      Accés obert
      This paper reports an experimental study and subsequent constitutive modelling focused on the stress-strain and volumetric response during deviatoric stress application of a partially saturated clayey-silt. The material ...

    • Modeling the behavior of gas hydrate bearing sediments 

      Sánchez, Marcelo; Shastri, Ajay; Gai, Xerui; Santamarina, J. Carlos (Universitat Politècnica de Catalunya. Departament d'Enginyeria del Terreny, Cartogràfica i Geofísica, 2015-06-02)

    • On the hydration of unsaturated barriers for high-level nuclear waste disposal 

      Gens Solé, Antonio; Pomaro, Beatrice; Sánchez, Marcelo; Villar Galicia, María Victoria (The Hong Kong University of Science and Technology (HKUST), 2018)
      Text en actes de congrés
      Accés obert
      The paper addresses the topic of the effects of hydration and temperature on the final state of an engineered barrier composed of compacted bentonite. In particular the distributions of water content and dry density are ...

    • Water retention behaviour of an embankment model 

      Zielinski, M.; Sánchez, Marcelo; Romero Morales, Enrique Edgar; Sentenac, P. (American Society of Civil Engineers (ASCE), 2011)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The depth of the unsaturated zone is strongly influenced by environmental factors. Approximately two-thirds of the world has sufficiently hot or arid climatic conditions so that the unsaturated zone forms more than a ...
