  • 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 ...

  • Stabilization of clayey soil using fibre reinforcement 

    Trabelsi, Houcem; Chebbi, M; Guiras, H.; Jamei, Mehrez; Romero Morales, Enrique Edgar (The Hong Kong University of Science and Technology (HKUST), 2018)
    Conference report
    Open Access
    The paper presents experimental and numerical investigations on crack evolution during desiccation, on unsaturated, compacted and reinforced clay using natural Alfa fibres. The effect of fibre content is investigated and ...

  • Ice formation in unsaturated frozen soils 

    Mao, Yanxin; Romero Morales, Enrique Edgar; Gens Solé, Antonio (The Hong Kong University of Science and Technology (HKUST), 2018)
    Conference report
    Open Access
    This paper presents a procedure for determining unfrozen water saturation in a partially saturated frozen soil (clayey silt) using bulk electrical conductivity (EC) measurements. A modification of Archie’s law is proposed ...

  • Hygroscopicity issues in powder and grain technology 

    Torres Serra, Joel; Romero Morales, Enrique Edgar; Rodríguez Ferran, Antonio (The Hong Kong University of Science and Technology (HKUST), 2018)
    Conference report
    Open Access
    The effect of hygroscopicity on flowability of powders and bulk solids with applications in the packaging industry is experimentally and numerically investigated. Firstly, four granular materials are tested at different ...

  • Inclusion of chemical effect in a fully coupled THM finite element code 

    Abed, A. A.; Solowski, W; Romero Morales, Enrique Edgar; Gens Solé, Antonio (The Hong Kong University of Science and Technology (HKUST), 2018)
    Conference lecture
    Open Access
    Bentonite-rich clays can be used as a buffer / backfill material in deep geological repositories for nuclear waste. The prediction of the long-term performance of a buffer / backfill in such a complex environment, where ...

  • Three-dimensional analysis of penetration problems using G-PFEM 

    Monforte Vila, Lluís; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; Carbonell Puigbó, Josep Maria (CRC Press, 2018)
    Conference lecture
    Restricted access - publisher's policy
    Numerical simulation of large displacement problems in geomechanics has attracted the interest of many researchers over the past decades. In many circumstances these problems can be treated as two dimensional: plane stress ...
