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 ... -
