  • A subloading surface clay and sand model 

    Pinedo Vilcahuamán, Paul José; Monforte Vila, Lluís; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2023)
    Conference report
    Open Access
    The mechanical response of natural soils is characterized by a narrow elastic domain, a smooth transition between elastic to elasto-plastic regime, and hysteretic behaviour during cyclic loading. These realistic features ...
  • Digital image-based analysis of a small-scale dam failure during wetting 

    Morales Flauzín, Gerardo; Pinyol Puigmartí, Núria Mercè; Lloret Morancho, Antonio (EDP Sciences, 2023)
    Conference report
    Open Access
    The use of digital images and the correlation of them in time is commonly used in geotechnical laboratory experiments to measure surface variables in a non-invasive and massive way. Digital image correlation-based methods ...
  • Exploring material heterogeneity in gas flow simulation through clay materials: a numerical study 

    Sayad Noghretab, Babak; Puig Damians, Ivan; Olivella Pastallé, Sebastià; Gens Solé, Antonio (2023)
    Conference lecture

    This paper presents the results of the initial molding of the large-scale gas injection test 1 (Lasgit) conducted at the Äspö Hard Rock Laboratory in Sweden. Lasgit is a field test that follows the Swedish KBS-3V disposal ...
  • Modelling soil-vegetation-atmosphere in a field experiment 

    Badakhshan, Ehsan; Vaunat, Jean (2023)
    Conference report
    Restricted access - publisher's policy
    In this paper, a soil-atmosphere-vegetation interaction, comprised of the state of the atmosphere and its interactions with vegetation in terms of precipitation, wind, temperature, and radiation, is used based on a Finite ...
  • Exploring viscous effects on numerical simulations of static liquefaction triggering 

    Pinedo Vilcahuamán, Paul José; Besenzon, Davide; Mánica Malcom, Miguel Ángel; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (Gecamin, 2022)
    Conference lecture
    Restricted access - publisher's policy
    Failures due to static liquefaction have been too frequent in tailings dams. Stress-deformation numerical analyses based on critical state theory are able to reproduce those failures and may be used to gain insight into ...
  • A time-to-facture DEM model for simulating creep in rough crushable sand 

    Lei, Jiangtao; Arroyo Alvarez de Toledo, Marcos; Ciantia, Matteo Oryem; Zhang, Ningning (2023)
    Conference lecture
    Open Access
    A contact model able to capture creep of crushable sands within a discrete element method (DEM) framework is presented. Time dependency is established through stress-corrosion induced grain fracture. This is grafted onto ...
  • Influence of numerical model mesh properties on predicted in soil temperature, relative humidity and degree of saturation of reinforced soil structures 

    Moncada Ramírez, Aníbal Andrés; Puig Damians, Ivan; Olivella Pastallé, Sebastià; Bathurst, Richard (2022)
    Conference lecture
    Restricted access - publisher's policy
    Geosynthetic materials are routinely used in soil reinforcement and stabilization applications. They have proven to be an important part of the sustainable solution for reinforced soil walls (RSWs). For RSW constructed ...
  • Strength reduction analysis in polymeric reinforced soil walls 

    Moncada Ramírez, Aníbal Andrés; Puig Damians, Ivan; Olivella Pastallé, Sebastià; Bathurst, Richard John (2023)
    Conference lecture
    Restricted access - publisher's policy
    The latest revision of EN-1997 allows for the use of numerical tools to design geotechnical structures, provided limit state conditions are thoroughly evaluated were analysis of the construction and post-construction stages ...
  • Coupled modelling of environmental in-soil conditions and their effects over polyester straps reinforced soil structures 

    Moncada Ramírez, Aníbal Andrés; Puig Damians, Ivan; Olivella Pastallé, Sebastià; Bathurst, Richard John (2022)
    Conference lecture
    Restricted access - publisher's policy
    Polyester (PET) strap reinforcement materials are being routinely used as soil reinforcement for mechanically stabilized earth (MSE) walls. Strength and stiffness of the polyester fibres can be expected to decrease with ...
  • Modelling the effect of in-soil temperature and relative humidity on performance of PET strap soil reinforcement products 

    Moncada Ramírez, Aníbal Andrés; Puig Damians, Ivan; Olivella Pastallé, Sebastià; Bathurst, Richard John (2021)
    Conference lecture
    Restricted access - publisher's policy
    Polyester (PET) strap reinforcement materials are now used routinely as soil reinforcement for mechanically stabilized earth (MSE) walls. Strength and stiffness of the polyester fibres can be expected to decrease with ...
  • Mitigación de grietas por desecación en suelos finos mediante el uso de fibras sintéticas 

    Hernández Valerio, Carolina; Botero Jaramillo, Eduardo; Encalada López, David Alejandro; Najdi, Abdallah; Prat Catalán, Pere; Ledesma Villalba, Alberto (Sociedad Mexicana de Ingeniería Geotécnica (SMIG), 2022)
    Conference report
    Restricted access - publisher's policy
    Los suelos arcillosos tienen la propiedad de hincharse en presencia de agua y contraerse en su ausencia, produciendo así grietas por desecación que alteran significativamente su desempeño mecánico e hidráulico. En este ...
  • Implementation of a fixed-location time lapse photogrammetric rock slope monitoring system in Castellfollit de la Roca, Spain 

    Matas Casado, Gerard; Prades Valls, Albert; Núñez Andrés, María Amparo; Buill Pozuelo, Felipe; Lantada, Nieves (Editorial UPV, 2022)
    Conference report
    Open Access
    When monitoring deformations in natural hazards such as rockfalls and landslides, the use of 3D models has become a standard. Several geomatic techniques allow the generation of these models. However, each one has its pros ...
