• 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 ...
    • Effects of Drilling for Tieback Anchors on Surrounding Ground: Results from Field Tests 

      Lande, Einar John; Karlsrud, Kjell; Langford, Jenny; Nordal, Steinar (Peer reviewed; Journal article, 2020)
      A full-scale field test program was carried out to investigate the effects of drilling for tieback anchors on the surrounding ground. The test anchors were drilled from the ground surface through a soft clay deposit and ...
    • 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 ...
    • Pore pressure reduction and settlements induced by deep supported excavations in soft clay 

      Langford, Jenny; Baardvik, Gunvor; Karlsrud, Kjell (Chapter, 2016)
      As a part of the large research project, "LimitingDamage" (BegrensSkade), common causes of damage or unexpectedly large settlements connected to ground and foundations works have been investigated. It can be seen that ...
    • 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 ...
