  • 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

    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 ...
  • A new efficient strategy to simulate particle breakage in DEM analyses 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; Calvetti, Francesco (2014)
    Conference report
    Restricted access - publisher's policy
    The discrete element method (DEM) is increasingly gaining acceptance as a modelling tool for engineering problems of direct geotechnical relevance. One area for which the method seems naturally well adapted is that of ...
  • Fluid effects in sand production simulations coupling DEM with CFD 

    Climent Pera, Natalia; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; O'Sullivan, Catherine (CRC Press Taylor & Francis Group, 2014)
    Conference report
    Restricted access - publisher's policy
    Sand production around a wellbore is here simulated using a three dimensional numerical model based on Discrete Element Method (DEM) coupled with Computational Fluid Dynamics (CFD). The model is calibrated against a ...

  • Explicit finite deformation stress integration of the elasto-plastic constitutive equations 

    Monforte Vila, Lluís; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; Carbonell Puigbó, Josep Maria (CRC Press Taylor & Francis Group, 2014)
    Conference report
    Restricted access - publisher's policy
    In this work, an explicit integration scheme for hyperelastic-based finite strains elasto-plasticity is presented. One step update equations are obtained from the large deformation multiplicative elasto-plasticity theory, ...
  • Hybrid minimization algorithm applied to tunnel back analysis 

    Santos Rodríguez, Cristian de; Ledesma Villalba, Alberto; Gens Solé, Antonio (CRC Press Taylor & Francis Group, 2014)
    Conference report
    Restricted access - publisher's policy
    The paper describes a procedure to perform backanalysis in an automatic manner in the context of a tunnel excavation. The measured displacements are compared with the calculated ones obtained from a Finite Element Analysis, ...
  • Small-strain shear stiffness of compacted clays: initial state and microstructural features 

    Suriol Castellví, Josep; Romero Morales, Enrique Edgar; Lloret Morancho, Antonio; Vaunat, Jean (CRC Press, 2014)
    Conference report
    Restricted access - publisher's policy
    The small-strain shear stiffness of compacted Barcelona silty clay is studied focusing on the effects of the initial state and the microstructure set on compaction. The Proctor plane is used to map these states, which cover ...
  • Freezing-thawing tests on natural pyroclastic samples 

    Pelaez, R.R; Casini, Francesca; Romero Morales, Enrique Edgar; Gens Solé, Antonio; Viggiani, Giulia M.B. (CRC Press, 2014)
    Conference report
    Restricted access - publisher's policy
    Artificial Ground Freezing is one of the construction techniques that were extensively adopted during construction of Line 1 of Napoli Underground, to ensure stability and waterproofing of the platform tunnels and inclined ...
