    • CPTU-detection of thin clay layers in sand: Results from calibration chamber tests 

      Skrede, Hallvard; Hammer, H.B.; Nordal, S.; L'Heureux, Jean-Sébastien (Chapter, 2022)
      The detection of thin clay layers (i.e. ≲ 20 cm) is challenging for all conventional geotechnical field investigations techniques, including high quality CPTU tests. During the last two years, a research program has been ...

    • Effect of the scatter between CPTU measured parameters in soil classification 

      Paniagua Lopez, Ana Priscilla; L'Heureux, Jean-Sébastien (Chapter, 2022)
      Using piezocones from different manufacturers may yield different results even if the equipment complies with international standards. This causes problems when soil investigation contractors, using different cones, operate ...

    • Evaluation of sample disturbance of three Norwegian clays 

      Paniagua, P; L'Heureux, Jean-Sébastien; Carroll, Roselyn; Kåsin, Kristoffer; Sjursen, Morten Andreas; Amundsen, Helene A. (Chapter, 2017)
      The quality and reliability of laboratory test data in sensitive clay can significantly be affected by sample disturbance. In turn, sample disturbance may affect key design parameters such as compressibility, preconsolidation ...

    • Lessons learned from the 2015 Soerkjosen shoreline landslide in Norway 

      L'Heureux, Jean-Sébastien; Skotheim, Arne Åsmund; Emdal, Arnfinn; Lyche, Einar; Christensen, Stein Olav; Hellum, Øyvind S. (Chapter, 2017)
      Soft and partly sensitive clays along the fjords of northern Norway pose a challenge for infrastructure. Learning from failures is essential in providing guidelines for future geotechnical work in such areas. A shoreline ...

    • Norway's National GeoTest Site Research Infrastructure (NGTS) 

      L'Heureux, Jean-Sébastien; Lunne, Tom; Lacasse, Suzanne; Carroll, Roselyn; Strandvik, Stein Oddvar; Instanes, Arne; Sinitsyn, Anatoly; Degago, Samson Abate; Nordal, Steinar (Chapter, 2017)
      Benchmarking is a key to the reliability of the solutions in geotechnical engineering, both for testing and verifying innovative soil investigation methods and verifying and calibrating foundation solutions. NGI and its ...

    • Thin-layer detection from the cone resistance rate of change 

      Hammer, H. B.; Nordal, S.; L'Heureux, Jean-Sébastien; Skrede, Hallvard (Chapter, 2022)
      True determination of soil parameters for thin clay layers in sand or silts from CPTU measurements is challenging. Cone resistance in thin layers is influenced by the surrounding layers resulting in unrepresentative ...
