    Minor thesis
    Open Access
    Les argiles de Trièves (França) són objecte de nombrosos desordres urbanístics i rurals degut a la gran quantitat de moviments de vessant que hi tenen lloc. A Mas d'Avignonnet s'han realitzat nombrosos estudis per tal de ...
  • Drying induced effects on the residual strength of remoulded clays 

    Merchán, V; Vaunat, Jean; Romero Morales, Enrique Edgar (Taylor & Francis, 2009)
    Conference report
    Open Access
    Experimental tests on residual shear strength of clays using “high suction control system” have shown that the friction angle significantly increases at high suction, and that such an increase is more significant as the ...
  • Efecto de los cambios de succión y tensión en la degradación de argilitas 

    Gómez Ramírez, Susana (Universitat Politècnica de Catalunya, 2008-06-30)
    Minor thesis
    Open Access
    El objetivo principal del estudio geotécnico realizado en esta tesina se basa en la determinación de los efectos provocados por variaciones en la succión y en la tensión sobre una roca blanda. El estudio se fundamenta ...

    Romero Morales, Enrique Edgar; Alonso Pérez de Agreda, Eduardo; Marschall, P; Arnedo Gaute, Diego; De Gracia, M (2009)
    Conference lecture
    Open Access
    Understanding gas transport processes is one of the key issues in the assessment of radioactive waste repository performance and is the focus of this research. To this aim, this research programme was started with ...
  • Heating pulse tests under constant volumen on natural Boom clay. 

    Lima, Analice; Romero Morales, Enrique Edgar; Gens Solé, Antonio; Muñoz, Juan Jorge; Li, Xiangling (Science Press, 2010-08-20)
    Article
    Open Access
    Boom clay formation is a potential natural host rock for geological disposal of high-level nuclear waste in Belgium. Heating pulse tests with controlled power supply (maximum temperature was limited to 85°C) and controlled ...

    This paper shows the results of an experimental programme aimed at evaluating the low-strain shear modulus of a stiff clay (Boom clay, Belgium) and its dependency on water content changes (or, alternatively, degree of ...
  • Physical and geotechnical properties of clay phyllites 

    Garzón, E.; Sánchez-Soto, P.J.; Romero Morales, Enrique Edgar (2010)
    Article
    Restricted access - publisher's policy
    An experimental programme is presented with the aim of characterising –from physical, microstructural and geotechnical perspectives– the main properties of compacted clay phyllites. These clay phyllites are widely used as ...
  • The effect of drying-wetting cycles on the seismic properties of an anisotropic claystone 

    Mitaritonna, Giuseppina; Pineda, Jubert Edgar; Arroyo Alvarez de Toledo, Marcos; Romero Morales, Enrique Edgar (2009)
    Conference report
    Open Access
    The evolution of bar and shear wave velocities during a drying wetting cycle on a claystone is presented. There is a clear relationship with total suction, established by means of the material water retention curve. The ...
