    • Ageing effects on the stiffness behaviour of a microbiologically treated and compacted soil 

      Morales, Laura; Romero Morales, Enrique Edgar; Pineda Jiménez, Jubert Andrés; Garzon, E.; Giménez, Antonio (Springer, 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The paper describes an experimental study aimed at evaluating the evolution of some mechanical properties, specifically small-strain stiffness and unconfined compressive strength, induced by ageing after a microbiological ...

    • Effect of intermediate stress on collapse behaviour of a compacted clayey silt 

      Cárdenas, Octavio; Romero Morales, Enrique Edgar; Lloret Morancho, Antonio; Suriol Castellví, Josep (Springer, 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      There are few experimental results on the influence of the intermediate principal stress on the behaviour of unsaturated soils. Particularly, the effect of intermediate stress on the collapse response of a soil subjected ...

    • Influence of rainfall on the deformation and stability of a slope in overconsolidated clays: a case study 

      Alonso Pérez de Agreda, Eduardo; Gens Solé, Antonio; Delahaye, Carlos Héctor (Springer, 2003)
      Article
      Accés obert
      The behaviour of an instrumented unstable slope in a profile of weathered overconsolidated clay has been analysed. Available field investigation data and laboratory tests were integrated in a coupled hydromechanical model ...

    • Microstructural model for delayed deformation of clay: loading history effects 

      Alonso Pérez de Agreda, Eduardo; Navarro Gámir, Vicente (2005-04)
      Article
      Accés restringit per política de l'editorial
      Microstructural observations of clayey soils indicate that clay particles are aggregated in units of low internal porosity (microporosity). Larger voids (macroporosity) between those units are associated with the flow of ...

    • Simulation of cement-improved clay structures with a bonded elasto-plastic model: A practical approach 

      Arroyo Alvarez de Toledo, Marcos; Ciantia, Matteo Oryem; Castellanza, Riccardo; Gens Solé, Antonio; Nova, Roberto (2012-09)
      Article
      Accés restringit per política de l'editorial
      Engineering practice has usually dealt with the treated soil bodies using simplistic constitutive models (e.g. elastic perfectly-plastic Mohr–Coulomb). In this paper, a more refined bonded elasto-plastic model is here ...
