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 (Journal article; Peer reviewed, 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 ... -
Behaviour of 60-year-old trial embankments on peat
Long, Michael; Paniagua Lopez, Ana Priscilla; Grimstad, Gustav; Sponås, Egil Berg Antoniazzi; Bjertness, Endre; Ritter, Stefan (Peer reviewed; Journal article, 2023)The search for low cost solutions for roads on peatlands inspired the construction of four full scale trial embankments at two sites in Norway in the early 1960's. The embankments are still accessible and this work was ... -
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 ... -
Effectiveness of resistivity cone penetration tests in salt-treated highly sensitive clay
Helle, Tonje Eide; Long, Michael; Nordal, Steinar; Aagaard, Per (Journal article, 2017)Salt wells filled with potassium chloride may be used as landslide mitigation in highly sensitive quick clays, as the changed pore-water composition permanently improves the remoulded shear strength. To verify improvements, ... -
Investigation of Development of the Earth Pressure Coefficient at Rest in Clay During Creep in the Framework of Hyper-Viscoplasticity
Grimstad, Gustav; Long, Michael; Dadrasajirlou, Davood; Ghoreishian Amiri, Seyed Ali (Peer reviewed; Journal article, 2021)The in situ earth pressure coefficient at rest (K0) for clay has been widely discussed in the literature. In engineering practice, the empirical relationships between K0, the overconsolidation ratio (OCR), and the normally ... -
On the use of sawdust and wood chips in geotechnical engineering - Laboratory characterization
Bjertness, Endre; Sponås, Egil Berg (Master thesis, 2021)I 1963 og 1964 ble to forsøksfelt opprettet av Norges Geotekniske Institutt (NGI) og Statens vegvesen med den hensikt å undersøke setninger på torv. Sirkulære fyllinger av sand inkluderende sagmugglag med tykkelse på 1.0–2.0 ... -
Prediction of embankment settlement on Swedish peat using the soft soil creep model
Long, Michael; Grimstad, Gustav; Trafford, Andrew (Peer reviewed; Journal article, 2020)Despite the prevalence of peat in northern areas of Europe and elsewhere, there are comparatively few case histories of carefully monitored embankments constructed directly on peat. In addition the use of relatively advanced ... -
Stabilisation of Soft Clay, Quick Clay and Peat by Industrial By-Products and Biochars
Hov, Sølve; Paniagua Lopez, Ana Priscilla; Sætre, Christian; Long, Michael; Cornelissen, Gerard; Ritter, Stefan (Peer reviewed; Journal article, 2023)The stabilisation of soft soils using the traditional binders cement and quicklime are known to emit large amounts of carbon dioxide. To reduce this carbon footprint, substitutes such as industrial by-products have been ...
