A geochemical, mineralogical and geotechnical characterization of the low plastic, highly sensitive glaciomarine clay at Dragvoll, Norway
Helle, Tonje Eide; Aagaard, Per; Nordal, Steinar; Long, Michael; Bazin, Sara (Peer reviewed; Journal article, 2019)The sediments at the NTNU research site Dragvoll, Trondheim, Norway accumulated in seawater close to the glacier front during the Pleistocene-Holocene transition. A comprehensive site investigation and laboratory test ... -
A procedure for the assessment of the undrained shear strength profile of soft clays
Thakur, Vikas Kumar Singh; Fauskerud, Odd Arne; Gjelsvik, Vidar; Christensen, Stein Olav; Oset, Frode; Nordal, Steinar; Viklund, Margareta; Strand, Stein-Are (Chapter, 2016)In the geotechnical research community, there is widespread agreement that the choice of the characteristic undrained shear strength (cuA) is very important and plays an essential role in the design and stability analysis ... -
Effect of piezocone penetration rate on the classification of Norweian silt
Bihs, Annika; Nordal, Steinar; Long, Michael; Paniagua Lopez, Ana Priscilla; Gylland, Anders Samstad (Chapter, 2018)Interpretation of Cone Penetration Tests (CPTU) in intermediate soils is complex due to partially drained conditions during penetration. In order to gain more insight into the material behavior of silt during a CPTU, an ... -
Effects of Drilling for Tieback Anchors on Surrounding Ground: Results from Field Tests
Lande, Einar John; Karlsrud, Kjell; Langford, Jenny; Nordal, Steinar (Peer reviewed; Journal article, 2020)A full-scale field test program was carried out to investigate the effects of drilling for tieback anchors on the surrounding ground. The test anchors were drilled from the ground surface through a soft clay deposit and ... -
Formulation of non-coaxial plastic dissipation and stress–dilatancy relations for geomaterials
Tsegaye, Anteneh Biru; Benz, Thomas; Nordal, Steinar (Peer reviewed; Journal article, 2020)Stress–dilatancy theories play a central role in the modeling of the plastic dissipation of geomaterials. There exist several mathematical frameworks for describing the stress–dilatancy behavior of soils. One of the limiting ... -
Investigation of the change in soil fabric during cone penetration in silt using 2D measurements
Paniagua Lopez, Ana Priscilla; Fonseca, Joana; Gylland, Anders Samstad; Nordal, Steinar (Peer reviewed; Journal article, 2017) -
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. ... -
Multi-Temporal Satellite Image Composites in Google Earth Engine for Improved Landslide Visibility: A Case Study of a Glacial Landscape
Lindsay, Erin; Frauenfelder, Regula; Ruther, Denise Christina; Rubensdotter, Brita Lena Eleonor Fredin; Strout, James Michael; Nordal, Steinar (Peer reviewed; Journal article, 2022) -
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) -
Physical modelling of pile drilling in sand
Lande, Einar John; Ritter, Stefan; Tyvold, Henning Fürst; Nordal, Steinar (Peer reviewed; Journal article, 2021)Drilling for foundation piles and tieback anchors through soils using a continuous casing to support the borehole is often referred to as "overburden drilling". Monitoring data from several case studies show that overburden ... -
Site characterisation and some examples from large scale testing at the Klett quick clay research site
Long, Mike; L Heureux, Jean-Sebastien; Bache, Bjørn Kristian Fiskvik; Lund, Alf Kristian; Hove, Svein; Sødal, Karl Gunnar; Amundsen, Helene Alexandra; Nordal, Steinar; Montafia, Alberto (Peer reviewed; Journal article, 2019)The Klett research site was developed in conjunction with the new E6 developments south of Trondheim, Norway. The site comprises non-sensitive clay to about 6 m to 8 m and quick clay with significant silt lenses below this ...
