    Article
    Accés restringit per política de l'editorial
    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
    Accés restringit per política de l'editorial
    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
    Accés restringit per política de l'editorial
    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
    Accés restringit per política de l'editorial
    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

    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
    Accés restringit per política de l'editorial
    The KBS-3H disposal alternative is composed by horizontally placed supercontainers comprising the canisters with the spent nuclear fuel surrounded in both drift axis and radial directions by compacted bentonite blocks ...
  • SDMT-based numerical analyses of deep excavation in soft soil 

    Mariano, Alessandra di; Amoroso, Sara; Arroyo Alvarez de Toledo, Marcos; Monaco, Paola; Gens Solé, Antonio (2019-01)
    Article
    Accés obert
    The paper explores the application of conventional (DMT) and seismic (SDMT) dilatometer tests to an important case of deep excavation design. The work presents finite-element analyses simulating a deep excavation close to ...
  • Coupled CFD–DEM method for undrained biaxial shear test of methane hydrate bearing sediments 

    Jiang, Mingjing; Shen, Zhifu; Zhou, Wei; Arroyo Alvarez de Toledo, Marcos; Zhang, Wangcheng (2018-11)
    Article
    Accés restringit per política de l'editorial
    Methane hydrate (MH), a potential source of future energy, is extensively deposited in marine sediments. It is essential to understand the mechanical properties of methane hydrate bearing sediments (MHBS) for applications ...
  • Foundation of a gravity dam on layered soft rock: shear strength of bedding planes in laboratory and large "in situ" tests 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè; Pineda Jiménez, Jubert Andrés (2014-12)
    Article
    Accés restringit per política de l'editorial
    A 100 m high gravity dam (Castrovido dam, Burgos, Spain) is founded on a soft Weald red claystone with inter-bedded sandstone strata. Claystone weathering was identified in vertical and horizontal profiles of water content ...
  • Small scale slope failure benchmark test: modelling and prediction 

    Hoffmann Jauge, Christian; Meler Payán, Nuria; Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (Elsevier, 2014)
    Article
    Accés obert
    A benchmark was designed with the aim of evaluating the capabilities of current modelling techniques and computational codes to reproduce slope failures. Laboratory tests and three instrumented small scale experiments of ...
  • Mathematical modelling of slopes 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè; Yerro Colom, Alba (Elsevier, 2014)
    Article
    Accés obert
    The paper discusses first the effect of rainfall on the stability of slopes and it focusses on the role of permeability. Existing or induced discontinuities are shown to have a remarkable effect on the slope safety. Also, ...
  • Heave of a building induced by swelling of an anhydritic Triassic claystone
