An attempt to monitor pore pressure changes in a block sample during and after sampling
Amundsen, Helene A.; Jønland, Jan; Emdal, Arnfinn; Thakur, Vikas Kumar Singh (Journal article; Peer reviewed, 2017)A soil sample goes through stress changes during and after sampling. Sensitive clays are affected by sample disturbance and stress changes have a great effect on the quality. The reduction of in-situ total stresses to zero ... -
Application of machine learning to the identification of quick and highly sensitive clays from cone penetration tests
Godoy Leiva, Cristian Andres; Depina, Ivan; Thakur, Vikas Kumar Singh (Peer reviewed; Journal article, 2020)Geotechnical classification is vital for site characterization and geotechnical design. Field tests such as the cone penetration test with pore water pressure measurement (CPTu) are widespread because they represent a ... -
Back calculation of Debris flow Run-Out & Entrainment Using the Voellmy Rheology
Bayissa, Lemessa Fille (Master thesis, 2017)Debris flow is one of the many geo-hazards that cause a major damage worldwide. It can cause loss of human lives especially to those living in mountainous regions. Besides, it cause economic damage by destroying properties ... -
Effects of soil heterogeneity on susceptibility of shallow landslides
Oguz, Emir Ahmet; Depina, Ivan; Thakur, Vikas Kumar Singh (Peer reviewed; Journal article, 2021)Uncertainties in parameters of landslide susceptibility models often hinder them from providing accurate spatial and temporal predictions of landslide occurrences. Substantial contribution to the uncertainties in landslide ... -
Effects of storage on 54 mm piston samples of soft sensitive clay
Amundsen, Helene Alexandra; Thakur, Vikas Kumar Singh (Chapter, 2017)Effects of storage on low plasticity sensitive soft clay were studied by means of laboratory tests. The 54 mm fixed piston sampler was used, and the samples were stored in stainless steel tubes. When comparing the preliminary ... -
Effekt av lagringstid for 54 mm sylinderprøver av leire fra Tiller
Tovslid, Helge (Master thesis, 2015)I enkelte perioder får geotekniske laboratorier inn flere prøver enn de har kapasitet til teste, noe som fører til at prøvene må lagres. I tillegg er det vanlig at prøvetakingen foregår hele arbeidsuken før alle prøvene ... -
Engineering characterization of a leached marine clay using Sherbrooke block samples
Amundsen, Helene Alexandra; Emdal, Arnfinn Johannes; Thakur, Vikas Kumar Singh (Chapter, 2016)A detailed characterization of the leached marine clay at Rissa, North-West of Trondheim in Norway, is presented. The site lies just a few hundred meters away from the location where the well-known Rissa slide occurred in ... -
Experimental and Numerical Investigation of One-Dimensional Infiltration into Unsaturated Soil
Oguz, Emir Ahmet; Robinson, Katherine Emily; Depina, Ivan; Thakur, Vikas Kumar Singh (Chapter, 2021)Infiltration characteristics of an unsaturated soil are of interest in both seepage and stability analyses and should be evaluated carefully. In this study, a new large-scale one-dimensional infiltration column test setup ... -
Field and laboratory study of stress relief due to unloading in block samples of sensitive clay
Amundsen, Helene Alexandra; Emdal, Arnfinn; Thakur, Vikas Kumar Singh (Peer reviewed; Journal article, 2019)A block sample goes through stress changes during and after sampling. Sensitive clays are affected by sample disturbance and stress changes have a great effect on sample quality. Reduction of the in-situ total stresses to ... -
Flow Behaviour of Fine-Grained Soils
Adamson, Matthew (Master thesis, 2017)Estimating the propagation and run-out distances of a landslide is a crucial part of risk assessment and mitigation for infrastructure development in Norway. Computational and numerical models are currently being developed ... -
Implementation of non-newtonian rheology for debris flow simulation with REEF3D
Fornes, Petter; Bihs, Hans; Thakur, Vikas Kumar Singh; Nordal, Steinar (Journal article, 2017)Landslides triggered by hydro-meteorological processes are a serious natural hazard in many areas of the world. The landslides of the debris flow type are often triggered by extreme precipitation events. These landslides ... -
