  • A sequential algorithm for feed-forward neural networks with optimal coefficients and interacting frequencies 

    Romero Merino, Enrique; Alquézar Mancho, René (2005-10)
    External research report
    Open Access
    An algorithm for sequential approximation with optimal coefficients and interacting frequencies (SAOCIF) for feed-forward neural networks is presented. SAOCIF combines two key ideas. The first one is the optimization of ...
  • Run-out of landslides in brittle soils: an MPM anlysis 

    Yerro Colom, Alba; Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (CRC Press, 2014)
    Conference report
    Restricted access - publisher's policy
    In this paper a slope stability problem due to an increase of the pore pressure is analysed by means of the material point method (MPM). A strain softening model is implemented and the progressive failure is examined in ...
  • 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 ...
  • Patterns of cracking in soils due to drying and wetting cycles 

    Ledesma Villalba, Alberto; Cordero Arias, Josbel Andreina; Cuadrado Cabello, Agustín; Prat Catalán, Pere (CRC Press, 2014)
    Conference report
    Restricted access - publisher's policy
    There is a well reported evidence of cracking in clayey or silty soils when drying. Shrinkage in the soil mass and also boundary conditions generate a nonhomogeneous stress state locally producing tensile stresses and ...
  • Anisotropic features on the thermal conductivity of a deep argillaceous formation 

    Romero Morales, Enrique Edgar; Sau Valenzuela, Núria; Lima, Analice; Van Baelen, H; Sillen, X.; Li, Xiang Ling (IOS Press, 2015)
    Conference report

    An experimental study on Ypresian clays – one of the potential deep and sedimentary clay formations in Belgium for the geological disposal of heat-emitting radioactive waste – has been undertaken to systematically study ...
  • Drying cracks in soils: current advances and challenges 

    Romero Morales, Enrique Edgar; Sanchez, Marcelo; Kim, Sewon; Guimarães, Leonardo do N; Zielinski, Marcin; Atique, Alvis; Manzoli, Osvaldo (2015)
    Conference report
    Restricted access - publisher's policy
    This paper presents some current advances and challenges related to the behavior of soil subjected to drying and the consequent formation and propagation of cracks in the soil mass. Typical geotechnical problems associated ...
  • Gas migration and coupled hydro-mechanical issues in claystones for radioactive waste disposal at great depth 

    Romero Morales, Enrique Edgar; González Blanco, Laura; Marschall, Paul (European Association of Geoscientists & Engineers (EAGE), 2015)
    Conference report
    Restricted access - publisher's policy
    The hydro-mechanical behaviour of shales is becoming an important issue in current energy-related geomechanical investigations, such as CO2 sequestration, extraction of gas shale and nuclear waste geological storage. ...
  • 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 ...
  • Cracking behaviour of silty clay soil under drying-wetting cycles 

    Cordero Arias, Josbel Andreina; Prat Catalán, Pere; Ledesma Villalba, Alberto; Cuadrado Cabello, Agustín (Librairie Ifsttar, 2015)
    Conference report
    Restricted access - publisher's policy
    This paper presents the results and analysis of cracking tests carried on samples of silty clay which were subjected to a drying-wetting-drying cycle to study the effect of cyclic change of moisture on the cracking behaviour. ...
  • Observations of tool wear and excavation performance in urban tunnels 

    González Paez, Claudia; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2016)
    Conference report
    Restricted access - publisher's policy
    One of the most important predictions in a mechanized excavation project is the performance of the excavation Rostami et al., (1994), Bilgin & Balci, (2005). To obtain an efficient ground excavation in mechanized excavation ...
