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 ... -
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 ...
