  • 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 ...
  • 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. ...
  • 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 ...
  • Efecto de las condiciones iniciales de compactación dinámica en la presión de preconsolidación de un suelo 

    Gómez, Evelyn J.; Lloret Morancho, Antonio (2015)
    Conference lecture
    Restricted access - publisher's policy
    Esta investigación se centra en el estudio del comportamiento mecánico de un suelo compactado, con especial énfasis en la caracterización del parámetro de la presión de preconsolidación en estado saturado. Para lograr este ...
  • Studying collapse behaviour of sandy silt under generalised stress conditions 

    Cárdenas, Octavio E.; WEBER, R; Romero Morales, Enrique Edgar; Lloret Morancho, Antonio; Suriol Castellví, Josep (IOS Press, 2016)
    Conference lecture
    Restricted access - publisher's policy
    This paper presents preliminary results on the collapse response of an artificially prepared sand-silt mixture in a hollow cylinder apparatus. The wetting stage is performed under constant mean and deviatoric stresses but ...
  • Numerical study of the use of actively-tensioned polymeric strips for reinforced soil walls 

    Puig Damians, Ivan; Bathurst, Richard; Lima, Juan; Lloret Morancho, Antonio; Josa Garcia-Tornel, Alejandro (Institution of Civil Engineers (ICE), 2015)
    Conference report
    Restricted access - publisher's policy
    Polymeric strip reinforced soil walls require a practical method to fix the reinforcement tail-ends in the soil backfill during construction to ensure adequate anchorage and to avoid any slack along the linear reinforcement ...
