  • 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 ...
  • Feasibility of a soft biological improvement of natural soils used in compacted linear earth construction 

    Morales, Laura; Romero Morales, Enrique Edgar; Jommi, Cristina; Garzón Garzón, Eduardo; Giménez Fernández, Antonio (2015-02)
    Article
    Restricted access - publisher's policy
    Increasing demand for infrastructures requires innovative, cheap and environmental sustainable practices in construction. The soils which are available on site for linear embankments often need to be improved to satisfy ...
  • Characterization of gas flow through low-permeability claystone: laboratory experiments and two-phase flow analyses 

    Senger, Rainer; Romero Morales, Enrique Edgar; Ferrari, Alessio; Marschall, Paul (2014-04)
    Article
    Restricted access - publisher's policy
    For the characterization of gas migration through a low-permeability clay host rock for deep underground repositories, a comprehensive understanding of the relevant phenomena of gas and fluid flow through low-permeability ...
  • A new high-pressure triaxial apparatus for inducing and tracking hydro-mechanical degradation of clayey rocks 

    Pineda Jiménez, Jubert Andrés; Romero Morales, Enrique Edgar; Alonso Pérez de Agreda, Eduardo; Pérez Revilla, Tomás (2014-11)
    Article
    Restricted access - publisher's policy
    This paper presents the development of a new high-pressure triaxial apparatus specifically prepared for inducing and tracking the degradation of clayey rocks. Total suction—used to induce the hydraulic degradation—is applied ...
  • Suction effects on the residual shear strength of clays 

    Romero Morales, Enrique Edgar; Vaunat, Jean; Merchán, Vladimir (2014)
    Article
    Restricted access - publisher's policy
    The paper presents an experimental study on the residual shear strength of different clayey soils at varying total suctions. In a first part of the paper some insight into the behaviour of residual shear strength of a ...
  • Chemo-hydro-mechanical behaviour of compacted Boom Clay: joint effects of osmotic and matric suctions 

    Mokni, Nadia; Romero Morales, Enrique Edgar; Olivella Pastallé, Sebastià (Thomas Telford, 2014-07)
    Article
    Restricted access - publisher's policy
    An experimental programme involving osmotic and matric suction controlled tests is carried out to investigate the effects of increasing pore fluid concentration, chemical cycling (salinisation/dilution) and matric suction ...
  • An experimental study on the compaction and collapsible behaviour of a flood defence embankment fill 

    El Mountassir, G.; Sánchez, Marcelo; Romero Morales, Enrique Edgar (2014-09)
    Article
    Restricted access - confidentiality agreement
    With renewed interest in the performance of flood embankments globally, it is important that the performance of fills in conditions similar to 'as-constructed' are scrutinised. The fill material investigated in this study ...
  • 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
    Restricted access - publisher's policy
    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 ...
