  • 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 ...
  • Mecanismos de expansión en rocas sulfatadas 

    Ramon Tarragona, Anna (2015)
    Article
    Restricted access - author's decision
    Los mecanismos que conducen al hinchamiento en túneles en rocas sulfatadas se han descrito en la literatura; sin embargo, se propone una interpretación alternativa. La precipitación de cristales de yeso en discontinuidades ...
  • 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 ...
  • Caisson failure induced by wave action 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè; Fernández, P. (2015-08-29)
    Part of book or chapter of book
    Restricted access - publisher's policy
    In 2001 a storm induced the failure of four caissons recently built for the construction of a dyke in a new entrance to the Barcelona Harbor. Understanding the failure required the analysis of the construction history and ...
  • Recent developments of the Material Point Method for the simulation of landslides 

    Alonso Pérez de Agreda, Eduardo; Yerro Colom, Alba; Pinyol Puigmartí, Núria Mercè (2015-09)
    Article
    Open Access
    The paper describes first the theoretical framework of a "single layer" three phase material. The formulation is general and particular cases are dry and fully saturated soils. The formulation and discretization of the ...
  • 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 ...
  • A permafrost test on intact gneiss rock 

    Duca, S; Alonso Pérez de Agreda, Eduardo; Scavia, Claudio (Elsevier, 2015-07)
    Article
    Restricted access - publisher's policy
    Changes in permafrost conditions in high mountain rocks have increased the risk of dangerous instabilities. Ice segregation within the rock mass has been interpreted as one of the mechanisms involved in high mountain bedrock ...
  • 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
    Restricted access - publisher's policy
    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 ...
