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.

    Part of book or chapter of book
    Restricted access - publisher's policy
    The localization of strains in landslide shearing surfaces may induce relevant weakening processes due to the thermal pressurization of the pore water filling the pores. The associate reduction in strength can explain the ...

    Part of book or chapter of book
    Restricted access - publisher's policy
    The aim of this chapter is to show the capabilities of MPM to simulate geotechnical problems dealing with soil excavation. The stability of supported vertical excavation in elasto-plastic material is analyzed. Results are ...
  • Landslide motion assessment including rate effects and thermal interactions: revisiting the Canelles landslide 

    Alvarado Bueno, Mauricio; Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (2019-09)
    Article
    Open Access
    The re-activation of a large (40 Mm3) landslide on the valley slopes of a reservoir motivated a research initiative to estimate the risk of a fast-sliding mass moving into the reservoir. A previous simplified analysis had ...
  • Modelling gas flow experiments in Mx80 bentonite: analysis of preferential gas paths 

    Puig Damians, Ivan; Olivella Pastallé, Sebastià; Gens Solé, Antonio (International Centre for Numerical Methods in Engineering (CIMNE), 2019)
    Conference report
    Open Access
    A gas injection test, performed on compact bentonite, was carried out at the British Geological Survey. The test is composed by two stages (i.e. hydration followed by gas injection testing). After gas breakthrough and a ...

    A gas injection test performed on compact bentonite was carried out at the British Geological Survey. The test is composed of two stages (i.e. hydration followed by gas injection). After gas breakthrough and a period of ...
  • Assessment of earth retaining wall sustainability: value functions and stakeholder weighting sensitivity 

    Puig Damians, Ivan; Bathurst, Richard; Lloret Morancho, Antonio; Josa Garcia-Tornel, Alejandro; El Mansouri, D. (Springer Nature, 2019)
    Conference report
    Restricted access - publisher's policy
    Earth retaining walls are common geotechnical structures with a wide range of solutions available to perform the same function. More and more, geotechnical engineers are asked to find the best solution among several options ...

    The FEBEX in situ experiment was a full-scale test reproducing the near-field of an underground nuclear waste repository. It was performed in a gallery excavated in granite, two heaters simulated the thermal effect of the ...
  • Micromechanical inspection of incremental behaviour of crushable soils 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; O'Sullivan, Catherine; Gens Solé, Antonio (Springer, 2019-10)
    Article
    Open Access
    In granular soils grain crushing reduces dilatancy and stress obliquity enhances crushability. These are well-supported specimen-scale experimental observations. In principle, those observations should reflect some peculiar ...
  • Soil surface boundary condition in desiccating soils 

    Cuadrado Cabello, Agustín; Encalada López, David Alejandro; Ledesma Villalba, Alberto; Prat Catalán, Pere (The Icelandic Geotechnical Society (IGS), 2019)
    Conference report
