    Municipal solid waste is sometimes stored in baled form either before or after treatment. General design requirements for MSW landfills, such as slope stability and lining long-term integrity are still relevant for bale ...
  • THM analysis of compacted clay liner response to baled municipal waste 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Isus, Andreu (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Heat is generated in municipal waste containment facilities due to the chemical and biochemical evolution of waste. Sometimes it is required to check if the level of heat generated during the deposit lifetime may damage ...
  • Periodic cells for large-scale problem initialization 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Zhang, Ningning; Emam, Sacha (EDP Sciences, 2017)
    Text en actes de congrés
    Accés obert
    In geotechnical applications the success of the discrete element method (DEM) in simulating fundamental aspects of soil behaviour has increased the interest in applications for direct simulation of engineering scale boundary ...
  • Numerical analysis of desiccation, shrinkage and cracking in low plasticity clayey soils 

    Levatti, Hector Ulises; Prat Catalán, Pere; Ledesma Villalba, Alberto (2017)
    Comunicació de congrés
    Accés obert
    This paper presents a numerical study of the desiccation processes of low-plasticity clayey soils that usually result in shrinkage and often in cracking. For the theoretical development of the numerical model, concepts of ...
