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) -
GeoSuite – A Modular System for Geotechnical Design
Lacasse, Suzanne; Jostad, Hans Petter; L'Heureux, Jean-Sébastien; Torgersrud, Øyvind; Sandven, Rolf Birger (Chapter, 2016)Remarkable advances in the analysis tools of, for example slopes, embankment stability and settlements have happened since the 90s. Many are due to the information technology revolution in all aspects of geotechnical ... -
Halden research site - Site characterisation and engineering properties of Halden silt
Blaker, Øyvind (NGI-Rapport;20160154-05-R, Report, 2019-10-02)Halden silt site is property of Halden municipality and it is known locally as Rødsparken. As part of the fully characterization of Halden silt site during NGTS project, two main reports are prepared: 1) a factual report ... -
Impact of data acquisition parameters and processing techniques on S-wave velocity profiles from MASW – Examples from Trondheim, Norway
Sauvin, Guillaume; Vanneste, Maarten; L'Heureux, Jean-Sébastien; O'Connor, P; O'Rourke, S.; O'Connell, Y.; Long, M. (Chapter, 2016)The shear modulus is one of the most important engineering parameters, and it relates directly to the soil's shear-wave velocity. Shear-wave velocities can be derived from both laboratory measurements (e.g., bender elements) ... -
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 ... -
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 ... -
Monotonic and dilatory excess pore water dissipations in silt following CPTU at variable penetration rate
Paniagua López, Ana Priscilla; Carroll, Roselyn; L'Heureux, Jean-Sébastien; Nordal, Steinar (Chapter, 2016)The relationship between cone penetration rate and pore pressure decay is investigated through dissipation tests following penetration at different rates. Field tests and model scale tests in the laboratory are performed. ... -
