  • The material point method for unsaturated soils 

    Yerro Colom, Alba; Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (Thomas Telford, 2015-03)
    Article
    Open Access
    The paper describes a three-phase single-point material point method formulation of coupled flow (water and air) for hydro-mechanical analysis of geotechnical problems involving unsaturated soils. The governing balance and ...
  • Trends in large-deformation analysis of landslide mass movements with particular emphasis on the material point method 

    Soga, Kenichi; Alonso Pérez de Agreda, Eduardo; Yerro Colom, Alba; Kumar, K.; Bandara, S. (Thomas Telford, 2016-03)
    Article
    Restricted access - publisher's policy
    Traditional geotechnical analyses for landslides involve failure prediction (i.e. onset of failure) and the design of structures that can safely withstand the applied loads. The analyses provide limited information on the ...
  • Wear and abrasivity: observations from EPB drives in mixed soft – rock sections 

    González Paez, Claudia; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2015-06)
    Article
    Restricted access - publisher's policy
    This paper summarizes the main observations related to geotechnical properties and tool changes that characterize the different tunnel drives in a database of 33 km of EPB tunnel records from the Barcelona area. The data ...
  • Modelling fluid flow in opalinus clay excavation damage zone: a semi-analytical approach 

    Alcoverro Bassols, Jordi; Olivella Pastallé, Sebastià; Alonso Pérez de Agreda, Eduardo (2014-12)
    Article
    Restricted access - publisher's policy
    The HG-A in situ test, located at the Mont Terri Underground Rock Laboratory (URL), was analysed as part of the FORGE project. This test investigated the behaviour of the excavation damage zone (EDZ) around a backfilled ...
  • 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 ...
