    • Artificial ground freezing of a volcanic ash: laboratory tests and modelling 

      Casini, F.; Gens Solé, Antonio; Olivella Pastallé, Sebastià; Viggiani, Giulia M.B. (2016-06)
      Article
      Accés obert
      The use of artificial ground freezing (AGF) to form earth support systems has had applications worldwide. These cover a variety of construction problems, including the formation of frozen earth walls to support deep ...

    • Breakage of an artificial crushable material under loading 

      Casini, Francesca; Viggiani, Giulia M.B.; Springman, Sarah Marcella (2013-10)
      Article

      The mechanical behaviour of granular materials depends on their grading. Crushing of particles under compression or shear modifies the grain size distribution, with a tendency for the percentage of fine material to increase. ...

    • Coupled phenomena induced by freezing in a granular material 

      Casini, Francesca; Gens Solé, Antonio; Olivella Pastallé, Sebastià; Viggiani, Giulia M.B. (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Artificial Ground Freezing (AGF) is a controllable process that can be used by engineers to stabilise temporarily the ground, provide structural support and/or exclude groundwater from an excavation until construction of ...

    • Freezing-thawing tests on natural pyroclastic samples 

      Pelaez, R.R; Casini, Francesca; Romero Morales, Enrique Edgar; Gens Solé, Antonio; Viggiani, Giulia M.B. (CRC Press, 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Artificial Ground Freezing is one of the construction techniques that were extensively adopted during construction of Line 1 of Napoli Underground, to ensure stability and waterproofing of the platform tunnels and inclined ...

    • Protecting surface and buried structures from tunnelling using pile walls: a prediction model 

      Franza, Andrea; Losacco, Nunzio; Ledesma Villalba, Alberto; Viggiani, Giulia M.B.; Jimenez Rodríguez, Rafael (2021-10)
      Article
      Accés obert
      When tunnelling poses excessive risks for buildings and buried foundations, a pile row barrier may shield the existing structure from ground movements. This paper presents a three-dimensional linear elastic prediction ...

    • Triaxial tests on frozen ground: formulation and modelling 

      Casini, F.; Gens Solé, Antonio; Olivella Pastallé, Sebastià; Viggiani, Giulia M.B. (2013)
