• Alternative binders for improvement of soft soils - a geoenvironmental approach 

      Jafarbiglookarami, Ali (Master thesis, 2021)
      Miljøspor fra menneskelige aktiviteter begynner å utgjøre mange problemer i vår nåværende verden. I mellomtiden kan sivilingeniør og spesifikt geoteknikk, som er ansvarlig for et bredt utvalg av menneskeskapte aktiviteter ...
    • 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 ...
    • Biochar amendment for improved and more sustainable peat stabilisation 

      Ritter, Stefan; Paniagua Lopez, Ana Priscilla; Hansen, Caroline Berge; Cornelissen, Gerard (Peer reviewed; Journal article, 2022)
      Carbon-intensive binders such as cement are traditionally employed to stabilise peat. Few studies have investigated alternative materials such as biochar to improve peat stability while simultaneously sequestering carbon ...
    • Comparing laboratory and field samples of lime-cement improved Norwegian clay 

      Paniagua Lopez, Ana Priscilla; Falle, F. A.; Sølve, Hov; Tekseth, Kim Robert Bjørk; Mirzaei, Fazel; Breiby, Dag Werner (Journal article; Peer reviewed, 2022)
    • 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 ...
    • Effect of the scatter between CPTU measured parameters in soil classification 

      Paniagua Lopez, Ana Priscilla; L'Heureux, Jean-Sébastien (Chapter, 2022)
      Using piezocones from different manufacturers may yield different results even if the equipment complies with international standards. This causes problems when soil investigation contractors, using different cones, operate ...
    • Engineering properties of Norwegian peat for calculation of settlements 

      Long, Mike; Paniagua Lopez, Ana Priscilla; Grimstad, Gustav; Trafford, Andrew; Degago, Samson Abate; L Heureux, Jean-Sebastien (Peer reviewed; Journal article, 2022)
      Despite some 9% of Norway's area being underlain by peat the geotechnical characteristics of the material have not been well documented. As peatlands form an excellent carbon sink there is much pressure on planning authorities ...
    • Evaluating geoparameters of Maine sensitive clay by CPTU 

      Mayne, P. W.; Paniagua Lopez, Ana Priscilla; Di Buo, B.; Agaiby, S. S. (Chapter, 2022)
      Using two sets of analytical solutions for CPTU in clays, a suite of theoretically-consistent geoparameters is shown to be in good agreement with independent laboratory and field test results obtained on sensitive Presumpscot ...
    • Full-flow CPT tests in a nearshore organic clay 

      Hov, Sølve; Borgström, K.; Paniagua Lopez, Ana Priscilla (Chapter, 2022)
    • 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 (Journal article; Peer reviewed, 2017)
      Interpretation of CPTU testing in silt is non-trivial because of the partially drained conditions that are likely to occur during penetration. A better understanding of the pore pressure generation/dissipation is needed ...
    • 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 ...
    • Verdal Port Landslide: Slope Stability Back Analysis from CPTU and Finite Element Modelling 

      Joe, Hayden (Master thesis, 2020)
      In January 2019, a shallow marine landslide occurred at Verdal Port, Norway. This slope failure occurred during ongoing construction for port expansion. The initial geotechnical investigations were heavily reliant on CPTU ...
