    • A microstructural model on the link between change in pore size distribution and wetting induced deformation in a compacted silt 

      Casini, Francesca; Vaunat, Jean; Romero Morales, Enrique Edgar (American Society of Civil Engineers (ASCE), 2013)
      Conference report
      Restricted access - publisher's policy
      The water retention curve expressed in terms of water content or degree of saturation and suction is hysteretic, stress path dependent (on void ratio), and depends on pore network. To properly describe its evolving nature, ...
    • Breakage of an artificial crushable material under loading 

      Casini, Francesca; Viggiani, Giulia M.B.; Springman, Sarah Marcella (2013-10)
      Article
      Restricted access - publisher's policy
      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)
      Conference report
      Restricted access - publisher's policy
      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
      Restricted access - publisher's policy
      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 ...
    • Hydromechanical behaviour of a silty sand from a steep slope triggered by artificial rainfall : from unsaturated to saturated conditions 

      Casini, Francesca; Serri, Víctor; Springman, Sarah Marcella (2013-01)
      Article
      Restricted access - publisher's policy
      This paper presents an experimental investigation aimed at studying the hydromechanical behaviour of a silty sand from a steep slope in Ruedlingen in the northeast of Switzerland, where a landslide-triggering experiment ...
    • Progressive emergence of double porosity in a silt during compaction 

      Casini, Francesca; Vaunat, Jean; Romero Morales, Enrique Edgar; Desideri, Augusto (CRC Press, 2013)
      Conference report
      Restricted access - publisher's policy
      The paper deals with an experimental investigation of water retention properties of a statically compacted unsaturated low plasticity silt. The objective is a deeper understanding of the evolution of an aggregate type ...
    • Triaxial tests on frozen ground: formulation and modelling 

      Casini, Francesca; Gens Solé, Antonio; Olivella Pastallé, Sebastià; Viggiani, Giulia (CIMNE, 2013)
      Conference report
      Open Access
      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 ...
