  • Geomechanical response of fractured reservoirs 

    Zareidarmiyan, Ahmad; Salaridad, Hossein; Vilarrasa Riaño, Víctor; De Simone, Silvia; Olivella Pastallé, Sebastià (2018-12)
    Article
    Open Access
    Geologic carbon storage will most likely be feasible only if carbon dioxide (CO2) is utilized for improved oil recovery (IOR). The majority of carbonate reservoirs that bear hydrocarbons are fractured. Thus, the geomechanical ...
  • Numerical and experimental study of initiation and propagation of desiccation cracks in clayey soils 

    Levatti, Hector Ulises; Prat Catalán, Pere; Ledesma Villalba, Alberto (Elsevier, 2019-01)
    Article
    Restricted access - publisher's policy
    This paper presents the fundamentals and the mathematical formulation to study desiccation cracking in soils based on Unsaturated Soil Mechanics as well as a numerical analysis of a previous desiccation test program. The ...
  • Effect of partial substitution of highly reactive mineral additions by nanosilica in cement pastes 

    da Silva Rego, Joao Henrique; Frias Rojas, Moises; Moragues Terrades, Amparo; Fernández Carrasco, Lucía; Romero Morales, Enrique Edgar; Sanchez de Rojas, Maria Isabel (2019-01)
    Article
    Open Access
    The phenomena involved in portland cement hydration and interactions with nanosilica are very complex and not yet fully understood. In addition, few papers have currently proposed to investigate the microstructure and ...
  • Toronto-York Spadina subway extension tunnelling under Schulich Building 

    Ramos Schneider, Gonzalo; García Molina, Ángel; Ledesma Villalba, Alberto; Raveendra, Ravi; Polo Orodea, Tomás (2019-02)
    Article
    Open Access
    Tunnelling under the York University Schulich Building was one of the milestones of the Toronto-York Spadina Subway Extension Project. The challenge was to bore the tunnel under a flagship building only one diameter below ...
  • The collapse of Space building 

    Caicedo Hormaza, Bernardo; Alonso Pérez de Agreda, Eduardo; Mendoza, C.; Alcoverro Bassols, Jordi (2019-03)
    Article
    Restricted access - publisher's policy
    On 12 October 2013, the 24-storey high ‘Space’ building collapsed in Medellín, Colombia. The building had a reinforced concrete structure founded on large-diameter piles with enlarged bases. During and after construction ...
  • Mechanical behavior of an unsaturated clayey silt: an experimental and constitutive modelling study 

    Romero Morales, Enrique Edgar; Sánchez, Marcelo; Gai, Xuerui; Barrera Bucio, Mauricio; Lloret Morancho, Antonio (2018-11)
    Article
    Open Access
    This paper reports an experimental study and subsequent constitutive modelling focused on the stress-strain and volumetric response during deviatoric stress application of a partially saturated clayey-silt. The material ...
  • On the choice of stress–strain variables for unsaturated soils and its effect on plastic flow 

    Gallipoli, Domenico; Grassl, P.; Wheeler, Simon; Gens Solé, Antonio (Elsevier, 2018-09)
    Article
    Restricted access - publisher's policy
    The net stress plus suction and the average skeleton stress plus modified suction are two alternative sets of energetically consistent stress variables for modelling the hydro-mechanical behaviour of unsaturated soils. ...
  • Hydraulic conductivity from piezocone on-the-fly: a numerical evaluation 

    Monforte Vila, Lluís; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; Carbonell Puigbó, Josep Maria (Institution of Civil Engineers (ICE), 2018-12)
    Article
    Restricted access - publisher's policy
    Permeability is important in many geotechnical applications. The current CPTu practice to obtain permeability values relies on dissipation tests, which are frequently slow and only linked to permeability through compressibility ...
  • Small-strain shear stiffness of compacted bentonites for engineered barrier system 

    Pintado Llurba, Xavier; Romero Morales, Enrique Edgar; Suriol Castellví, Josep; Lloret Morancho, Antonio; Madhusudhan, B. N. (Elsevier, 2019-06)
    Article
    Restricted access - publisher's policy
    The shear modulus (G) of two different bentonites was measured by means of a resonant column apparatus. The samples were compacted at different dry densities and degrees of saturation and tested with different confinement ...
  • Numerical simulation of the undrained stability of slopes in anisotropic fine-grained soils 

    Conesa, Sergi; Mánica Malcom, Miguel Ángel; Gens Solé, Antonio; Huang, Y. (2019-01)
    Article
    Restricted access - publisher's policy
    The undrained stability of slopes in anisotropic fine-grained soils is studied in this paper using the finite element method (FEM). A constitutive model is presented, able to account for the observed variation of undrained ...
  • Grading evolution and critical state in a discrete numerical model of Fontainebleau sand 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; O'Sullivan, Catherine; Gens Solé, Antonio; Liu, T. (Thomas Telford, 2019-01)
    Article
    Restricted access - publisher's policy
    Granular materials reach critical states upon shearing. The position and shape of a critical state line (CSL) in the compression plane are important for constitutive models, interpretation of in situ tests and liquefaction ...
  • Three dimensional thermo-hydraulic modelling for KBS-3H alternative 

    Puig Damians, Ivan; Olivella Pastallé, Sebastià; Pintado Llurba, Xavier (Elsevier, 2019-03)
    Article
