  • Performance of mixed formulations for the particle finite element method in soil mechanics problems 

    Monforte, LLuís; Carbonell Puigbó, Josep Maria; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (Springer, 2017-07)
    Article
    Accés obert
    This paper presents a computational framework for the numerical analysis of fluid-saturated porous media at large strains. The proposal relies, on one hand, on the particle finite element method (PFEM), known for its ...

    Ramon Tarragona, Anna; Alonso Pérez de Agreda, Eduardo; Olivella Pastallé, Sebastià (2017-09)
    Article
    Accés restringit per política de l'editorial
    Las expansiones ocurridas en el túnel de Lilla son el resultado del crecimiento de cristales de yeso en discontinuidades. Se describe un procedimiento de análisis numérico para el diseño de un túnel en roca anhidrítica ...
  • Hydro-chemo-mechanical modelling of tunnels in sulfated rocks 

    Ramon Tarragona, Anna; Alonso Pérez de Agreda, Eduardo; Olivella Pastallé, Sebastià (Thomas Telford, 2017-11)
    Article
    Accés restringit per política de l'editorial
    A modelling procedure to address the tunnel–anhydritic rock interaction is described in this paper. The model incorporates the basic physico-chemical phenomena involved in rock swelling, often observed during excavation ...
  • Protecting sensitive constructions from tunnelling: the case of World Heritage buildings in Barcelona 

    Ledesma Villalba, Alberto; Alonso Pérez de Agreda, Eduardo (Thomas Telford, 2017-10)
    Article
    Accés restringit per política de l'editorial
    Construction of the tunnel for the high-speed Madrid–Barcelona–France railway link across central Barcelona became a major technical and social challenge due to the impact of the tunnel on nearby historic buildings (two ...
  • Earthquake static stress transfer in the 2013 Gulf of Valencia (Spain) seismic sequence 

    Salo Salgado, Lluis; Frontera Genovard, Tànit; Goula Suriñach, Xavier; Pujades Beneit, Lluís; Ledesma Villalba, Alberto (2017-09-05)
    Article
    Accés obert
    On 24 September 2013, an Ml 3.6 earthquake struck in the Gulf of Valencia (Spain) near the Mediterranean coast of Castelló, roughly 1 week after gas injections conducted in the area to develop underground gas storage had ...
  • Numerical modelling of slope–vegetation–atmosphere interaction: an overview 

    Elia, Gaetano; Cotecchia, Federica; Pedone, Giuseppe; Vaunat, Jean; Vardon, Philip J.; Pereira, Carlos; Springman, Sarah Marcella; Rouainia, M.; Van Esch, John; Koda, Eugeniusz; Josifovski, Josif; Nocilla, Alessandra; Askarinejad, Amin; Stirling, Ross; Helm, Peter; Lollino, Piernicola; Osinski, Piotr (2017-08)
    Article
    Accés obert
    The behaviour of natural and artificial slopes is controlled by their thermo-hydro-mechanical conditions and by soil–vegetation–atmosphere interaction. Porewater pressure changes within a slope related to variable ...
  • Novel analysis for large strains based on particle image velocimetry 

    Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio (2017-07)
    Article
    Accés obert
    Over the last few decades, the particle image velocimetry (PIV) technique has become an interesting tool used to measure displacements in the field of experimental mechanics. This paper presents a procedure to interpret ...
  • Small strain shear moduli of unsaturated natural and compacted loess 

    Ng, C. W. W.; Kaewsong, R.; Zhou, C.; Alonso Pérez de Agreda, Eduardo (Thomas Telford, 2017-07)
    Article
    Accés restringit per política de l'editorial
    Suction and microstructure play critical roles in the mechanical behaviour of loess, yet their effects on small strain (from 0·001 to 1%) shear moduli are not fully understood. In this study, shear moduli of loess with ...
  • A procedure for the direct determination of Bishop's chi parameter from changes in pore size distribution 

    Vaunat, Jean; Casini, F. (Thomas Telford, 2017-07)
    Article
    Accés restringit per política de l'editorial
    Most of the recent works relating to the concept of effective stress in unsaturated soils focus on the proposal by Bishop, and, more particularly, on the search for suitable relationships between Bishop's ¿ parameter and ...
  • DEM modelling of cone penetration tests in a double-porosity crushable granular material 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Butlanska, Joanna; Gens Solé, Antonio (2016-03)
    Article
    Accés restringit per política de l'editorial
    A three-dimensional discrete element model is used to investigate the effect of grain crushing on the tip resistance measured by cone penetration tests (CPT) in calibration chambers. To do that a discrete analogue of pumice ...
  • Thrust and torque components on mixed-face EPB drives 

    González Paez, Claudia; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2016-08)
    Article
    Accés restringit per política de l'editorial
    In this communication we propose a method to estimate net thrust and torque applied at the excavation front by cutting tools from EPB machines when they are working in mixed faces constituted by soils and soft rock. The ...
  • Performance of the Opalinus Clay under thermal loading: experimental results from Mont Terri rock laboratory (Switzerland) 

    Gens Solé, Antonio; Wieczorek, Klaus; Gaus, Irina; Garitte, Benoit; Mayor, Juan Carlos; Schuster, Kristof; Armand, G.; Garcia Siñeriz, Jose luis; Trickl, Thomas (2017-04)
