    This paper extends the numerical parametric study previously reported by the writers for the vertical load distribution and vertical gap compression between facing panel units in steel reinforced soil walls ranging in ...
  • Modelling the mechanical behaviour of Callovo-Oxfordian argillite: formulation and application 

    Gens Solé, Antonio; Mánica Malcom, Miguel Ángel; Vaunat, Jean; Ruiz Restrepo, Daniel Felipe (Springer, 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The paper presents a constitutive model for argillaceous rocks, developed within the framework of elastoplasticity, that includes a number of features that are relevant for a satisfactory description of their hydromechanical ...
  • Heave of a building on Keuper anhydritic formation 

    Ramon Tarragona, Anna; Alonso Pérez de Agreda, Eduardo (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The development of fissures in a building placed at the site of an ancient quarry excavated in a Keuper formation motivated a detailed in-situ investigation of the foundation material. Severe fissures and cracks were present ...
  • Analysis of strain localization with a non-local plasticity model 

    Mánica Malcom, Miguel Ángel; Gens Solé, Antonio; Vaunat, Jean; Ruiz Restrepo, Daniel Felipe (2017)
    Text en actes de congrés
    Accés obert
    Strain localization can be defined as the accumulation of deformations in narrow zones, in the form of shear bands or cracks, commonly observed in several geomaterials like concrete, rocks, dense sands, or stiff fine-grained ...
  • Simulation of penetration problems in geomechanics 

    Gens Solé, Antonio; Arroyo Alvarez de Toledo, Marcos; Carbonell Puigbó, Josep Maria; Ciantia, Matteo Oryem; Monforte Vila, Lluís (2017)
    Text en actes de congrés
    Accés obert
    The simulation of penetration problems in geomaterials is a challenging problem as it involves large deformations and displacements as well as strong non-linearities affecting material behaviour, geometry and contact ...
  • A new re-usable shallow foundation for light loads: load tests and analysis 

    Tarragó, Dani; Gens Solé, Antonio; Rosas, Juan José (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2017)
    Text en actes de congrés
    Accés obert
    An innovative re-usable shallow foundation system for light loads has been developed consisting of a concrete block and four steel tubes driven into the ground at different orientations. The interaction between the block, ...
  • Backanalysis of preloading 

    Santos Rodríguez, Cristian de; Ledesma Villalba, Alberto; Gens Solé, Antonio (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2017)
    Text en actes de congrés
    Accés obert
    The paper presents the application of a backanalysis methodology to the inverse analysis of preloading soft clays. The methodology is based on an appropriate selection of the objective function and it uses a novel adaptive ...
  • Hydromechanical modelling of a tunnel excavated in argillaceous rock 

    Mánica Malcom, Miguel Ángel; Gens Solé, Antonio; Vaunat, Jean; Ruiz Restrepo, Daniel Felipe (Universität Innsbruck, 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The paper presents selected results from a hydromechanical analysis of an excavation at great depth in argillaceous rock. A constitutive model specifically developed for this type of materials has been used. It incorporates ...
  • Irreversible behaviour of crushable sands: a DEM study 

    Gens Solé, Antonio; Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The irreversible behaviour of crushable sands is investigated by means of a Discrete Element Method (DEM) analogue. The calculations have been performed using a recently developed procedure to simulate particle crushing ...
  • Mecanismos que controlan la velocidad de los deslizamientos
