  • Reaction of a pile group against deep swelling 

    Alonso Pérez de Agreda, Eduardo; Ramon Tarragona, Anna; Sauter, Simon (2015)
    Conference report
    Restricted access - publisher's policy
    A singular case of development of deep soil expansions in the vicinity of pile groups supporting bridge pillars motivated the analysis. A semi-analytic procedure, which uses some available fundamental solutions for cavity ...
  • Incorporating a microstructural state variable in constitutive modelling 

    Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo; Gens Solé, Antonio (2013)
    Conference report
    Restricted access - publisher's policy
    The selection of constitutive variables has been extensively discussed when modeling unsaturated soils. In general, suction and degree of saturation have been involved in the definition of constitutive variables. Recently, ...
  • An undrained upper bound solution for the face stability of tunnels reinforced by micropiles 

    Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (2013)
    Conference report
    Restricted access - publisher's policy
    Tunnel in difficult soils may require procedures to prevent tunnel face failures. Face stabilization can be achieved by the installation of some structural elements. This paper presents an analysis of face stability of ...
  • Sustainability assessment of earth retaining wall structures: preliminary model and simplified application 

    García Adroguer, Eduard; Puig Damians, Ivan; Josa Garcia-Tornel, Alejandro; Lloret Morancho, Antonio; Bathurst, Richard (2015)
    Conference report
    Restricted access - publisher's policy
    Earth retaining wall (RW) structures have been used for centuries but new technologies and innovations in materials continue to emerge. While different wall types can perform the same function, a rigorous sustainability ...
  • Highly expansive granular mixtures 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè; Hoffmann Jauge, Christian (CRC Press, 2014)
    Conference report
    Restricted access - publisher's policy
    The paper describes the behavior of mixtures of highly compacted bentonite pellets. They are considered as a suitable impervious and tight barrier for nuclear waste disposal. Laboratory experiments aimed at identifying the ...
  • Equivalent interface properties to model soil-facing interactions with zero-thickness and continuum element methodologies 

    Puig Damians, Ivan; Yu, Yan; Lloret Morancho, Antonio; Bathurst, Richard; Josa Garcia-Tornel, Alejandro (IOS Press, 2015)
    Conference lecture

    Soil-facing mechanical interactions play an important role in the behavior of earth retaining walls. Generally, numerical analysis of earth retaining structures requires the use of interface elements between dissimilar ...
  • Crystal growth and soil expansion: the role of interfacial pressure and pore structure 

    Ramon Tarragona, Anna; Alonso Pérez de Agreda, Eduardo (CRC Press, 2014)
    Conference report
    Restricted access - publisher's policy
    The paper summarizes first a set of field observations in connection with the severe heave experienced by Lilla tunnel excavated in a Tertiary anhydritic claystone. Heave and swelling pressures against the tunnel rigid ...
  • EPB tunnelling in mixed geological formations: a case study 

    Di Mariano, Alessandra; Gens Solé, Antonio (Taylor & Francis, 2014)
    Conference report
    Restricted access - publisher's policy
    Tunnels for the new Barcelona Metro Line 9 are being constructed in a densely built urban area, close to sensitive structures. The paper presents a case history involving tunnelling in difficult mixed geological conditions ...
  • THM analysis of pellet-based materials for engineered barriers for nuclear waste 

    Gens Solé, Antonio; Barboza De Vasconcelos, Ramon; Villar Galicia, María Victoria (Engineers Australia, 2014)
    Conference report
    Restricted access - publisher's policy
    A promising alternative to form engineered barriers for high level nuclear waste repositories is the use of pellets-based material because high dry densities can be achieved with no or minimal compaction effort. It is also ...
  • Importance of sample volume changes and material degradation on gas transport properties in Boom Clay 

    González Blanco, Laura; Romero Morales, Enrique Edgar; Li, Xiang Ling; Sillen, X. (Engineers Australia, 2014)
    Conference report
    Restricted access - publisher's policy
    An experimental study on Boom Clay –one of thepotential deep clay formationsin Belgium for the geological disposal of long-living and heat-emitting radioactive waste–has been performed using controlled volume-rate gas ...
