  • Mecanismos de expansión en rocas sulfatadas 

    Ramon Tarragona, Anna (2015)
    Article
    Restricted access - author's decision
    Los mecanismos que conducen al hinchamiento en túneles en rocas sulfatadas se han descrito en la literatura; sin embargo, se propone una interpretación alternativa. La precipitación de cristales de yeso en discontinuidades ...
  • Recent developments of the Material Point Method for the simulation of landslides 

    Alonso Pérez de Agreda, Eduardo; Yerro Colom, Alba; Pinyol Puigmartí, Núria Mercè (2015-09)
    Article
    Open Access
    The paper describes first the theoretical framework of a "single layer" three phase material. The formulation is general and particular cases are dry and fully saturated soils. The formulation and discretization of the ...
  • A permafrost test on intact gneiss rock 

    Duca, S; Alonso Pérez de Agreda, Eduardo; Scavia, Claudio (Elsevier, 2015-07)
    Article
    Restricted access - publisher's policy
    Changes in permafrost conditions in high mountain rocks have increased the risk of dangerous instabilities. Ice segregation within the rock mass has been interpreted as one of the mechanisms involved in high mountain bedrock ...
  • PSI deformation map retrieval by means of temporal sublook coherence on reduced sets of SAR images 

    Iglesias González, Rubén; Mallorquí Franquet, Jordi Joan; Monells Miralles, Daniel; López Martínez, Carlos; Fabregas Canovas, Francisco Javier; Aguasca Solé, Alberto; Gili Ripoll, José Antonio; Corominas Dulcet, Jordi (2015-01-01)
    Article
    Open Access
    Prior to the application of any persistent scatterer interferometry (PSI) technique for the monitoring of terrain displacement phenomena, an adequate pixel selection must be carried out in order to prevent the inclusion ...
  • Pile groups under deep expansion: a case history 

    Alonso Pérez de Agreda, Eduardo; Sauter, Simon; Ramon Tarragona, Anna (2015-08)
    Article
    Open Access
    A viaduct in a high speed railway line experienced severe heave of its central pillars as a result of deep expansion of an anhydrite rock. Bridge pillars were founded on pile groups which experienced vertical heave ...
  • 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 ...
