  • Modelling gas flow experiments in Mx80 bentonite: analysis of preferential gas paths 

    Puig Damians, Ivan; Olivella Pastallé, Sebastià; Gens Solé, Antonio (International Centre for Numerical Methods in Engineering (CIMNE), 2019)
    Conference report
    Open Access
    A gas injection test, performed on compact bentonite, was carried out at the British Geological Survey. The test is composed by two stages (i.e. hydration followed by gas injection testing). After gas breakthrough and a ...

    A gas injection test performed on compact bentonite was carried out at the British Geological Survey. The test is composed of two stages (i.e. hydration followed by gas injection). After gas breakthrough and a period of ...

  • Assessment of earth retaining wall sustainability: value functions and stakeholder weighting sensitivity 

    Puig Damians, Ivan; Bathurst, Richard; Lloret Morancho, Antonio; Josa Garcia-Tornel, Alejandro; El Mansouri, D. (Springer Nature, 2019)
    Conference report
    Restricted access - publisher's policy
    Earth retaining walls are common geotechnical structures with a wide range of solutions available to perform the same function. More and more, geotechnical engineers are asked to find the best solution among several options ...

  • Soil surface boundary condition in desiccating soils 

    Cuadrado Cabello, Agustín; Encalada López, David Alejandro; Ledesma Villalba, Alberto; Prat Catalán, Pere (The Icelandic Geotechnical Society (IGS), 2019)
    Conference report
    Restricted access - publisher's policy
    Soils undergoing desiccation exhibit shrinkage and eventually cracking. That may become an environmental problem in practical applications. From a Geotechnical perspective, it is possible to solve the corresponding ...

  • Modelling of fiber-reinforced concrete and application case 

    Puig Damians, Ivan; Olivella Pastallé, Sebastià; Cots Corominas, Carles (International Centre for Numerical Methods in Engineering (CIMNE), 2019)
    Conference report
    Open Access
    This report summarizes the first results of 2D and 3D finite element method numerical modelling analysis of fiber-reinforced concrete behaviour and a tunnel case study application. A porosity strength-dependant material ...

  • Bentonite strain due to cyclic suction changes 

    Villar Galicia, María Victoria; Lloret Morancho, Antonio (The Hong Kong University of Science and Technology (HKUST), 2018)
    Conference lecture
    Open Access
    A series of suction-controlled oedometer tests were performed on a highly compacted bentonite following drying/wetting and wetting/drying paths from the initial hygroscopic conditions (about 120 MPa) under low vertical ...

  • Hydro-mechanical modelling of an unsaturated seal structure 

    Ruiz Restrepo, Daniel Felipe; Vaunat, Jean; Gens Solé, Antonio; Mánica Malcom, Miguel Ángel (CRC Press, 2018)
    Conference report
    Restricted access - publisher's policy
    The paper contains a coupled numerical analysis of the hydration of a potential sealing system for isolating shafts, ramps and connecting galleries in a deep geological repository for high level nuclear waste. The modelling ...

  • Gas effect on CPTu and dissipation test carried out on natural soft-soil of Barcelona Port 

    Tarragó Munté, Daniel; Gens Solé, Antonio (CRC Press, 2018)
    Conference report
    Restricted access - publisher's policy
    There is abundant evidence that gas is present in the sediments of the prodelta of the Llobregat River in the area of the Barcelona Port. The presence of gas has been directly observed by gas releases and deflagrations ...

  • Permeability estimates from CPTu: a numerical study 

    Monforte Vila, Lluís; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; Parolini, C. (CRC Press, 2018)
    Conference report
    Restricted access - publisher's policy
    Realistic numerical simulations of CPTu in soft soils are now becoming possible thanks to methods like the Particle Finite Element Method (PFEM). They may be used to systematically explore the traditional methods of CPTu ...

  • Modeling of gas transport through bentonite taking into account subscale structures with process-dependent behaviour 

    Senger, Rainer; Namhata, Argha; Papafotiou, Alexandros; Marschall, Paul; Romero Morales, Enrique Edgar (2018)
    Conference report
    Restricted access - publisher's policy
    In many nuclear waste disposal concepts bentonite is used as a buffer material forming the near-field around the HLW canisters and the sealing material for the backfilled repository structures. The safety functions of the ...

  • Classifying granular materials for feeding performance using experimental and numerical techniques 

    Torres Serra, Joel; Caba, Joan; Rodríguez Ferran, Antonio; Romero Morales, Enrique Edgar (2018)
    Conference report
    Restricted access - publisher's policy
    Flowability of powders and bulk solids is critical for the packaging industry in the selection and design of bulk material handling equipment. Nowadays, a variety of feeder systems are used for dosing operations in bagging ...

  • On the hydration of unsaturated barriers for high-level nuclear waste disposal 

    Gens Solé, Antonio; Pomaro, Beatrice; Sánchez, Marcelo; Villar Galicia, María Victoria (The Hong Kong University of Science and Technology (HKUST), 2018)
    Conference report
    Open Access
    The paper addresses the topic of the effects of hydration and temperature on the final state of an engineered barrier composed of compacted bentonite. In particular the distributions of water content and dry density are ...
