    • An experimental study on the compaction and collapsible behaviour of a flood defence embankment fill 

      El Mountassir, G.; Sánchez, Marcelo; Romero Morales, Enrique Edgar (2014-09)
      Article
      Restricted access - confidentiality agreement
      With renewed interest in the performance of flood embankments globally, it is important that the performance of fills in conditions similar to 'as-constructed' are scrutinised. The fill material investigated in this study ...
    • Analysis of unsaturated materials hydration incorporating the effect of thermo-osmotic flow 

      Sánchez, Marcelo; Arson, Chloé; Gens Solé, Antonio; Aponte, Fernando (Elsevier, 2016-06)
      Article
      Open Access
      The geological disposal of a high level radioactive waste relies in a system composed of engineered and geological barriers. The soils and rocks involved in the design of this type of solution are generally initially ...

      Conference report
      Restricted access - publisher's policy
      The understanding of the coupled behaviour of highly active swelling clays is better achieved considering two structural levels and their interactions in the context of a double-porosity model. Hydraulic equilibrium between ...
    • Coupled hydro-mechanical fault reactivation analysis

      Conference report
      Restricted access - publisher's policy
      An appropriate understanding of the interaction and effects of thermal, hydraulic, mechanical and chemical (THMC) phenomena occurring in compacted swelling clay is greatly assisted by the development and use of coupled ...
    • 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
      Open Access
      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 (Centro Internacional de Métodos Numéricos en Ingeniería (CIMNE), 2011)
      Conference report
      Open Access
      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 ...

      Article
      Open Access
      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 ...
