  • Fostering sustainability and critical thinking through debate: a case study 

    Rodríguez Dono, Alfonso; Hernández Fernández, Antonio (2021-06)
    Article
    Open Access
    Transversal competences such as sustainability or critical thinking have become more important in the last decades in University teaching. The objective of this article is to assess the effectiveness of debate as a teaching ...
  • Microstructural model for delayed deformation of clay: loading history effects 

    Alonso Pérez de Agreda, Eduardo; Navarro Gámir, Vicente (2005-04)
    Article
    Restricted access - publisher's policy
    Microstructural observations of clayey soils indicate that clay particles are aggregated in units of low internal porosity (microporosity). Larger voids (macroporosity) between those units are associated with the flow of ...
  • The effect of curing conditions on the hydromechanical properties of a metakaolin-based soilcrete 

    Spagnoli, Giovanni; Romero Morales, Enrique Edgar; Fraccica, Alessandro; Arroyo Alvarez de Toledo, Marcos; Gómez Bonilla, Rodrigo Andrés (Thomas Telford, 2021-01)
    Article
    Restricted access - publisher's policy
    An attractive approach to reduce the carbon dioxide footprint of deep soil mixing (DSM) is to replace Portland cement-based binders by geopolymers based on metakaolin. Safe design requires a good understanding of the ...
  • Analysis and modelling of longitudinal deformation profiles of tunnels excavated in strain-softening time-dependent rock masses 

    Song, Fei; Rodríguez Dono, Alfonso; Olivella Pastallé, Sebastià; Zhong, Zhen (Elsevier, 2020-09)
    Article
    Restricted access - publisher's policy
    Rock mass behaviour model selection, in particular, to represent the post-failure behaviour and time-dependent behaviour of rock masses, are critical issues in the correct application of tunnelling design techniques such ...
  • Copper canister shearing in spent nuclear fuel repository using Bodner–Partom model 

    Khadivipanah, Peiman; Pintado, Xavier; Olivella Pastallé, Sebastià; Vaunat, Jean (Elsevier, 2020-05)
    Article
    Restricted access - publisher's policy
    This paper describes the implementation of the Bodner–Partom model for the analysis of copper corrosion barrier in canisters containing spent nuclear fuel. The Bonder–Partom constitutive model implemented in CODE_BRIGHT ...
  • Modelling engineered barriers for spent nuclear fuel repository using a double-structure model for pellets 

    Toprak, Erdem; Olivella Pastallé, Sebastià; Pintado, Xavier (2020-02)
    Article
    Open Access
    This paper describes an experimental programme and the corresponding modelling in order to characterise the hydromechanical (HM) behaviour of pellets. At least two levels of porosity can be distinguished in the pellets: ...
  • Consolidation of gas hydrate-bearing sediments with hydrate dissociation 

    de la Fuente Ruiz, Maria; Vaunat, Jean; Marín Moreno, Hector (EDP Sciences, 2020-11)
    Article
    Open Access
    Quantifying sediment deformation induced by depressurization of gas hydrate reservoirs and hydrate dissociation is crucial for the safe and economic production of natural gas from hydrates, and for understanding hydrate-related ...
  • Modelling advective gas flow in compact bentonite: lessons learnt from different numerical approaches 

    Tamayo Mas, Elena; Harrington, J. F.; Brüning, T.; Shao, H.; Dagher, E. E.; Lee, Jaewon; Kim, K.; Rutqvist, Jonny; Kolditz, Olaf; Lai, S. H.; Chittenden, C.; Wang, Y.; Puig Damians, Ivan; Olivella Pastallé, Sebastià (Elsevier, 2021-03)
    Article
    Open Access
    In a repository for radioactive waste hosted in a clay formation, hydrogen and other gases may be generated due to the corrosion of metallic materials under anoxic conditions, the radioactive decay of waste and the ...
  • A constitutive model for the accumulated strain of unsaturated soil under high-cycle traffic loading 

    Cao, Zhigang; Chen, Jingyu; Alonso Pérez de Agreda, Eduardo; Ramon Tarragona, Anna; Cai, Yuanqiang; Gu, Chuan; Zhang, Qi (2021-05)
    Article
    Restricted access - publisher's policy
    The road base is normally situated above the water table and thus in unsaturated state. Experimental results show that the accumulated strains of the unsaturated road base aggregate under high-cycle traffic loads are ...
  • Size effect on the hydraulic behavior of fluid flow through a single rough-walled fracture 

    Zhong, Zhen; Wang, Lei; Song, Leibo; Gao, Chao; Hu, Yunjin; Gao, Huicai; Song, Fei; Rodríguez Dono, Alfonso; Lou, Rong (Elsevier, 2021-04)
    Article
    Restricted access - publisher's policy
    This study provides a numerical approach to evaluate the effect of sample sizes on fluid flow through a single rough-walled fracture. The rough-walled fracture was generated by using mathematical statistics. Its aperture ...
  • The failure of the Aznalcóllar tailings dam in SW Spain 

    Alonso Pérez de Agreda, Eduardo (2021-03)
    Article
    Restricted access - publisher's policy
    The Aznalcóllar dyke failed and released much of its stored, saturated pyritic tailings after a process of progressive failure in the foundation clay. 1.5 Mm3 of tailings and 5.5 Mm3 of acidic water were rapidly discharged ...
  • Massive, continuous and non-invasive surface measurement of degree of saturation by shortwave infrared images 

    Parera Morales, Ferran; Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (2020-07)
    Article
    Open Access
    Short wave infrared (SWIR) images provide an accurate procedure to measure the degree of saturation (Sr) of soils. Changes in Sr result in reflectance changes which were recorded by a special digital camera optimized for ...
