El grup realitza recerca en mecànica de sòls i de les roques i en l'àmbit de la geomecànica en general. També és actiu en un ampli espectre de matèries d'enginyeria geològica i geotècnica, com ara l'estabilitat de talussos, els fonaments, les excavacions, els túnels, l'avaluació de riscos geològics i l'emmagatzematge de residus. La seva activitat en la mecànica de sòls no saturats i l'aplicació de mètodes numèrics avançats és àmpliament reconeguda.

The group carries out research in soil and rock mechanics and in the field of geomechanics in general. It is also active in a wide range of geological and geotechnical engineering fields, such as slope stability, foundations, excavations, tunnels, the evaluation of geological risks, and waste disposal. The group?s activity in unsaturated soil mechanics and in the application of advanced numerical methods is widely recognised.

Recent Submissions

  • Dynamics of slow and fast landslides 

    Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio; García Núñez, Luis Miguel (2020)
    Conference report
    Open Access
    The paper discusses some factors that control the shearing soil behaviour and the dynamics of landslides: strain-, strain rate-, and temperature effects. The strain rate effect on residual strength is discussed through ...
  • Microstructural model for delayed deformation of clay: loading history effects 

    Alonso Pérez de Agreda, Eduardo; Navarro Gámir, Vicente (2005-04)
    Article
    Restricted access - publisher's policy
    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 ...
  • The effect of curing conditions on the hydromechanical properties of a metakaolin-based soilcrete 

    Spagnoli, Giovanni; Romero Morales, Enrique Edgar; Fraccica, Alessandro; Arroyo Alvarez de Toledo, Marcos; Gómez Bonilla, Rodrigo Andrés (Thomas Telford, 2021-01)
    Article
    Restricted access - publisher's policy
    An attractive approach to reduce the carbon dioxide footprint of deep soil mixing (DSM) is to replace Portland cement-based binders by geopolymers based on metakaolin. Safe design requires a good understanding of the ...
  • Creep effects on the thermo-hydro-mechanical responses of Callovo-Oxfordian claystone 

    Vu, Minh-Ngoc; Souley, Mountaka; Alonso, Matías; Vaunat, Jean; Gens Solé, Antonio; Plúa, Carlos; de Lesquen, Christophe; Armand, G. (Springer, 2021)
    Part of book or chapter of book
    Restricted access - publisher's policy
    In France, a deep geological disposal for high-level radioactive waste (HLW) and intermediate level long life radioactive waste (IL-LLW) called Cigéo is planned to be constructed in a deep Callovo-Oxfordian claystone (COx) ...
  • Geomechanics of shale repositories: mechanical behavior and modeling 

    Mánica Malcom, Miguel Ángel; Ruiz Restrepo, Daniel Felipe; Vaunat, Jean; Gens Solé, Antonio (John Wiley & sons, 2020)
    Part of book or chapter of book
    Restricted access - publisher's policy
    This chapter presents an overview of modeling frameworks available within the theory of elastoplasticity and able to capture main features of shale behavior including: yield under compression, failure under deviatoric ...
  • Analysis and modelling of longitudinal deformation profiles of tunnels excavated in strain-softening time-dependent rock masses 

    Song, Fei; Rodríguez Dono, Alfonso; Olivella Pastallé, Sebastià; Zhong, Zhen (Elsevier, 2020-09)
    Article
    Restricted access - publisher's policy
    Rock mass behaviour model selection, in particular, to represent the post-failure behaviour and time-dependent behaviour of rock masses, are critical issues in the correct application of tunnelling design techniques such ...
  • Copper canister shearing in spent nuclear fuel repository using Bodner–Partom model 

    Khadivipanah, Peiman; Pintado, Xavier; Olivella Pastallé, Sebastià; Vaunat, Jean (Elsevier, 2020-05)
    Article
    Restricted access - publisher's policy
    This paper describes the implementation of the Bodner–Partom model for the analysis of copper corrosion barrier in canisters containing spent nuclear fuel. The Bonder–Partom constitutive model implemented in CODE_BRIGHT ...
  • Modelling engineered barriers for spent nuclear fuel repository using a double-structure model for pellets 

    Toprak, Erdem; Olivella Pastallé, Sebastià; Pintado, Xavier (2020-02)
    Article
    Open Access
    This paper describes an experimental programme and the corresponding modelling in order to characterise the hydromechanical (HM) behaviour of pellets. At least two levels of porosity can be distinguished in the pellets: ...
