Characterization and engineering properties of the NGTS Onsøy soft clay site
Gundersen, Aleksander; Hansen, Ragnhild; Lunne, Tom; L Heureux, Jean-Sebastien; Strandvik, Stein Oddvar (Peer reviewed; Journal article, 2019)In the 1960s, NGI investigated numerous potential research sites and established the first Onsøy soft clay site in 1968. In 2016, the NGTS project established five research sites, one of which is the NGTS Onsøy soft clay ... -
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 cone penetrometer type on CPTU results at a soft clay test site in Norway
Lunne, Tom; Strandvik, Stein Oddvar; Kåsin, Kristoffer; L'Heureux, Jean-Sébastien; Haugen, E.; Uruci, E.; Veldhuijzen, A.; Carlson, M.; Kassner, M. (Chapter, 2018)Seven different cone penetrometers from 5 manufacturers have been used in a comparative testing program at the Norwegian GeoTest site (NGTS) on soft clay in Onsøy, Norway. Tests with all cone types give very repeatable ... -
Engineering properties of low to medium overconsolidation ratio offshore clays
DeGroot, Don J.; Lunne, Tom; Ghanekar, Ravindra; Knudsen, Siren; Jones, Cody D.; Yetginer-Tjelta, Tor Inge (Peer reviewed; Journal article, 2019)This paper presents a summary of the geotechnical engineering properties of low to medium overconsolidation ratio offshore inorganic clays derived from a high quality database. These properties, such as preconsolidation ... -
Estimation of preconsolidation stress of clays from piezocone by means of high-quality calibration data
D'Ignazio, Marco; Lunne, Tom; Andersen, Knut H; Yang, Shaoli; Di Buò, Bruno; Länsivaara, Tim (Peer reviewed; Journal article, 2019)An extensive database of high-quality piezocone (CPTU) and laboratory oedometer test data on onshore and offshore clays worldwide has been established. The database covers a wide range of index parameters and overconsolidation ... -
Field verification tests of the newly developed flow cone tool—In-situ measurements of hydraulic soil properties
Gundersen, Aleksander Sæthereng; Carotenuto, Pasquale; Lunne, Tom; Walta, Axel; Sparrevik, Per (Peer reviewed; Journal article, 2019)Hydraulic soil properties, and in particular the hydraulic conductivity, is important in a number of geotechnical design cases. However, attention is often drawn towards the method of analysis rather than the quality and ... -
Impact of cone penetrometer type on measured CPTU parameters at 4 NGTS sites. Silt, soft clay, sand and quick clay
Gundersen, Aleksander S.; Lindgård, Anders; Lunne, Tom (NGI-rapport;20160154-21-R, Report, 2020-01-08)Using cone penetrometers from different manufacturers may yield different results even if the equipment complies with international standards. This report presents a study on differences in CPTU test results as function ... -
