    • 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
      Open Access
      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)

      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)

      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)
      Conference report

      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
      Open Access
      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)
      Conference report
      Open Access
