• CPTU correlations for Norwegian clays: an update 

      Paniagua Lopez, Ana Priscilla; D'Ignazio, Marco; L Heureux, Jean-Sebastien; Lunne, Tom; Karlsrud, Kjell (Peer reviewed; Journal article, 2019)
      Geotechnical design in clay areas in Norway is mainly based on piezocone (CPTU) tests results. Strength and stiffness parameters are usually derived from CPTU parameters and empirical correlations. In order to improve ...
    • Effect of piezocone penetration rate on the classification of Norweian silt 

      Bihs, Annika; Nordal, Steinar; Long, Michael; Paniagua Lopez, Ana Priscilla; Gylland, Anders Samstad (Chapter, 2018)
      Interpretation of Cone Penetration Tests (CPTU) in intermediate soils is complex due to partially drained conditions during penetration. In order to gain more insight into the material behavior of silt during a CPTU, an ...
    • Halden research site: geotechnical characterization of a post glacial silt 

      Blaker, Øyvind; Carroll, Roselyn; Paniagua Lopez, Ana Priscilla; DeGroot, Don J.; L Heureux, Jean-Sebastien (Peer reviewed; Journal article, 2019)
      This paper describes the geology and geotechnical engineering properties of the Halden silt; a 10–12 m thick deposit of fjord-marine, low plasticity clayey silt. Over the last six years, the test site has been well ...
    • Impact of sample quality on CPTU correlations in clay – Example from the Rakkestad clay 

      L'Heureux, Jean-Sébastien; Gundersen, Aleksander S.; D'Ignazio, Marco; Smaavik, Tone Fallan; Kleven, Arne; Rømoen, Magnus; Karlsrud, Kjell; Paniagua Lopez, Ana Priscilla; Hermann, Steinar (Chapter, 2018)
      As part of the zoning plan for the new 30 km long highway, E16, from Nybakk to Slomarka, an extensive laboratory and field testing campaign was conducted by NGI. The deposit along the highway is a normally to slightly ...
    • Investigation of the change in soil fabric during cone penetration in silt using 2D measurements 

      Paniagua Lopez, Ana Priscilla; Fonseca, Joana; Gylland, Anders Samstad; Nordal, Steinar (Peer reviewed; Journal article, 2017)
    • Strength and stiffness on lab-mixed specimens of stabilized Norwegian clays 

      Paniagua Lopez, Ana Priscilla; Bache, Bjørn Kristian Fiskvik; Karlsrud, Kjell; Lund, Alf Kristian (Peer reviewed; Journal article, 2019)
      In situ ground improvement by deep mixing the soil with stabilizing agents or binders as lime, cement, cement kiln dust or a combination of these is the most common method applied in the Nordic countries. In Norway, soil ...
    • Study on the practices for preconsolidation stress evaluation from oedometer tests 

      Paniagua Lopez, Ana Priscilla; L'Heureux, Jean-Sébastien (Chapter, 2016)
      The preconsolidation stress (pc') is determined from high-quality oedometer test results by a variety of interpretation methods. Sample quality in the database varies from very excellent to fair (i.e. class 1-2). Results ...
    • Variable rate of penetration and dissipation test results in a natural silty soil 

      Carroll, Roselyn; Paniagua Lopez, Ana Priscilla (Chapter, 2018)
      Variable rate of penetration over 1.2 to 1.5 m intervals were carried out in a natural clayey silt followed by dissipation tests. The tests are grouped into two main sets: an upper set from 5 to 6.5 m and a deeper set from ...
