    • Experimental study and numerical modelling of soil-roots hydro-mechanical interactions 

      Fraccica, Alessandro (Universitat Politècnica de Catalunya, 2019-12-09)
      Doctoral thesis
      Open Access
      Covenantee:   Université de Montpellier
      The thesis is aimed at characterising the multi-scale and hydro-mechanical behaviour of lightly compacted silty sand penetrated by a turf-grass (Cynodon Dactilon). The study will allow better assessing the impact of ...
    • Exploring the mechanical response of low-carbon soil improvement mixtures 

      Fraccica, Alessandro; Spagnoli, Giovanni; Romero Morales, Enrique Edgar; Arroyo Alvarez de Toledo, Marcos; Gómez Bonilla, Rodrigo Andrés (2022-05)
      Article
      Open Access
      As society moves towards decarbonisation, it is important to assess the hydromechanical behaviour of binders that could offer a low-carbon alternative to Portland cement in ground improvement technologies. This work considers ...
    • Monitoring of a full-scale embankment experiment regarding soil–vegetation–atmosphere interactions 

      Oorthuis Gómez, Raül; Hurlimann Ziegler, Marcel; Fraccica, Alessandro; Lloret Morancho, Antonio; Moya Sánchez, José; Puig i Polo, Càrol; Vaunat, Jean (2018-06)
      Article
      Open Access
      Slope mass-wasting like shallow slides are mostly triggered by climate effects, such as rainfall, and soil–vegetation–atmosphere (SVA) interactions play a key role. SVA interactions are studied by a full-scale embankment ...
    • Multi-scale effects on the hydraulic behaviour of a root-permeated and compacted soil 

      Fraccica, Alessandro; Romero Morales, Enrique Edgar; Fourcaud, Thierry (EDP Sciences, 2019)
      Conference report
      Open Access
      While roots have been generally proved to be beneficial to soil mechanical behaviour, different and counterposed results have been found when investigating their effects on soil hydraulic response. Roots affect the ...
    • Pérdida de suelo en laderas bajo cambio climático. procesos físicos, modelación predictiva y posibles estrategias de mitigación : el proyecto de investigación “Smucphy”

    • Slope orientation and vegetation effects on soil thermo-hydraulic behavior: an experimental study 

      Oorthuis Gómez, Raül; Vaunat, Jean; Hurlimann Ziegler, Marcel; Lloret Morancho, Antonio; Moya Sánchez, José; Puig i Polo, Càrol; Fraccica, Alessandro (2021-01)
      Article
      Open Access
      The stability and erosion of natural and man-made slopes is influenced by soil-vegetation-atmosphere interactions and the thermo-hydro-mechanical slope conditions. Understanding such interactions at the source of slope ...
    • Tensile strength of a compacted vegetated soil: laboratory results and reinforcement interpretation 

      Fraccica, Alessandro; Romero Morales, Enrique Edgar; Fourcaud, Thierry (Elsevier, 2021-12)
      Article
      Restricted access - publisher's policy
      So far, root reinforcement on soil has been primarily evaluated through direct shear and roots pull-out tests, while the effect of other stress paths and the behaviour at the soil–root¿ interface are still poorly investigated. ...
    • Tensile strength of a vegetated and partially saturated soil 

      Fraccica, Alessandro; Romero Morales, Enrique Edgar; Fourcaud, Thierry; Sondon Sansó, Mercedes; Gandarillas, Luis (EDP Sciences, 2020-10)
      Article
      Open Access
      Vegetated soil’s shear strength has been usually assessed through direct shear tests and under triaxial compression stress paths while less is known about its behaviour under tensile stress. Tensile strength and shrinkage-induced ...
    • TERRE project: interplay between unsaturated soil mechanics and low-carbon geotechnical engineering 

      Tarantino, A; El Mountassir, G.; Wheeler, Simon; Gallipoli, Domenico; Augarde, Charles; Urciuoli, Gianfranco; Romero Morales, Enrique Edgar; Priegue Mayán, Ángel Diego; Fraccica, Alessandro; Karagianni, Pavlina (EDP Sciences, 2020-10)
      Article
