    • A procedure for the direct determination of Bishop's chi parameter from changes in pore size distribution 

      Vaunat, Jean; Casini, F. (Thomas Telford, 2017-07)
      Article
      Accés obert
      Most of the recent works relating to the concept of effective stress in unsaturated soils focus on the proposal by Bishop, and, more particularly, on the search for suitable relationships between Bishop's ¿ parameter and ...

    • Characterisation and thermo-hydro-mechanical behaviour of unsaturated Boom clay: an experimental study 

      Romero Morales, Enrique Edgar (Universitat Politècnica de Catalunya, 1999-09-08)
      Tesi
      Accés obert
      El objetivo principal de esta investigación se centra en el análisis de los efectos de la temperatura y la hidratación o secado de las arcillas en el comportamiento de cambio de volumen, permeabilidad y características de ...

    • Chemo-hydro-mechanical behaviour of compacted Boom Clay: joint effects of osmotic and matric suctions 

      Mokni, Nadia; Romero Morales, Enrique Edgar; Olivella Pastallé, Sebastià (Thomas Telford, 2014-07)
      Article
      Accés restringit per política de l'editorial
      An experimental programme involving osmotic and matric suction controlled tests is carried out to investigate the effects of increasing pore fluid concentration, chemical cycling (salinisation/dilution) and matric suction ...

    • Hydromechanical behaviour of compacted granular expansive mixtures: experimental and constitutive study 

      Alonso Pérez de Agreda, Eduardo; Romero Morales, Enrique Edgar; Hoffmann Jauge, Christian (2011-04-01)
      Article
      Accés restringit per política de l'editorial
      Compacted granular mixtures of high-density bentonite pellets have been evaluated as an alternative buffer material to fill the empty space around nuclear waste disposal canisters in horizontal drifts. Despite the obvious ...

    • Soil desiccation cracks as a suction-contraction process 

      Cordero Arias, Josbel Andreina; Useche, G; Prat, P. C.; Ledesma Villalba, Alberto; Santamarina, J. C. (Institution of Civil Engineers (ICE), 2017-12)
      Article
      Accés obert
      Recent macro- and particle-scale advances in unsaturated soil behaviour have led to an enhanced understanding of the effects of moisture changes on soil response. This research examines desiccation cracks as a suction–co ...

    • The soft foundation soils of new breakwaters at the port of Barcelona 

      Alonso Pérez de Agreda, Eduardo; Gens Solé, Antonio; Madrid, R; Uzcanga, J (IOS Press, 2007)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The outer breakwaters of the new Barcelona harbour are currently under construction. Two types of breakwater are used: the classical trapezoidal rockfill structures and vertical caissons. The foundation soils are relatively ...
