Forankring av brofundament ved bruk av gyste fjellstag for opptak av statiske og sykliske laster
(Master thesis, 2016)I løpet av de siste årene er idéen om en fergefri kystriksvei fra Kristiansand via Bergen til Trondheim blitt en viktig politisk sak for mange av partiene på Stortinget, og Statens vegvesen har satt i gang mange tekniske ... -
Gyste fjellankre utsatt for syklisk belastning fra store brukonstruksjoner og vurdering av designkapasitet
(Master thesis, 2018)Statens Vegvesen planlegger å gjøre E-39 ferjefri. I tilknytning til dette prosjektet er det ønskelig å bruke gyste fjellankre til å avlaste store brufundamenter, der det sykliske bidraget ikke kan neglisjeres. I forbindelse ... -
Investigation of Geotechnical Properties of TBM Spoil from the Follo Line Project
(Master thesis, 2018)In connection to the Follo line tunnel project this thesis investigate some of the existing experience on use of TBM spoil as a construction aggregate. Compaction control tests provided by Bane NOR for the deposit at Åsland ... -
Isogeometric Analysis of Thermo-Hydro-Mechanically Coupled Processes in Soil
(Master thesis, 2016)This thesis conducts numerical studies on THM (Thermo-Hydro-Mechanically) coupled problems, using isogeometric elements and two models created at NTNU. One model is for fully saturated porous media, and the second is ... -
Jordskjelvberegning i henhold til Eurokode 8 og PLAXIS 2D
(Master thesis, 2015)Denne oppgaven tar for seg bruk av numeriske analyser med elementprogrammet PLAXIS 2D som er brukt til jordskjelvberegninger for tre ulike modeller. Hensikten er å undersøke hvordan dette korresponderer med Eurokode 8, ... -
Kryp i frossen jord
(Master thesis, 2018)Frossen jord er jord med temperatur under 0°C og kan beskrives som en naturlig kompositt bestående av mineralkorn, ufrosset vann, is og luft. Til sammen utgjør disse elementene et komplekst viskoplastisk materiale med svært ... -
Macro-model description and model verification
(Master thesis, 2017)The interaction between structures and soil is often idealized to simplify the problem. However, the soil structure interaction (SSI) is important for accurately predicting the mechanical behavior of foundations. Through ... -
Measuring Negative Pore Pressures in Partially Frozen Saturated Soils
(Master thesis, 2017)Freezing of soil is an issue which has many implications on modern infrastructure, in which frost heave plays a pivotal role. During freezing the behavior of the soil and the flow of water is altered. In an engineering ... -
Mitigation of Uncertainties in Rainfall-Induced Landslide Prediction Models in a Changing Climate - Kvam Case Study
(Master thesis, 2017)One of the main challenges in providing consistent and accurate predictions of rainfall-induced landslides is the large uncertainty involved in the assessment. This thesis demonstrates the potential of an alternative ... -
Model Testing and Rheology of a Fine Grain Rich Debris Flow
(Master thesis, 2018)Debris flows are a hazardous type of landslide, primarily caused by intense precipitation in steep mountainous terrain. Water, soil and debris mix to form a slurry that advances rapidly downslope, growing in size as it ... -
Modelling of Undrained Clay Subjected to Cyclic Loading - Semi-Explicit Material Model
(Master thesis, 2016)A material model, based on total stresses, has been developed to represent the undrained cyclic behavior of clay for finite element analyses. The material be- havior is split into an average- and a cyclic part, formulated ... -
Modelling Thawing Slope Stability of Arctic Coast
(Master thesis, 2016)Through a literature study, different aspects of frozen ground, physical properties, mechanical behavior of frozen ground, the relation between permafrost and climate, and erosional processes are described. The mechanical ... -
Numerical Framework for Modeling Cyclic Degradation of Soils
(Master thesis, 2017)For many years fatigue in soils has been a major design challenge. Due to cyclic loading the material behavior changes and permanent deformations are observed. Although explicit cyclic calculation methods exists, none are ... -
Numerical Modelling of a Pile Model Test with Focus on Small-strain Stiffness
(Master thesis, 2015)This thesis investigated the dynamic characteristics of a 1:20 scale model of a monopile offshore wind turbine foundation, and performed numerical modelling of the model pile using the FEM-software PLAXIS 3D. The build-up ... -
Nyttegjøring og gjenbruk av kalk-/sementstabilisert leire i deponier
(Master thesis, 2017)Kalk-/sementstabilisering er en mye brukt metode for å stabilisere sensitiv leire i dag. Ved innblanding av bindemiddel med leire, vil jorda få økt styrke og stabilitet. Deler av denne massen graves opp igjen ved etablering ... -
On Shear Wave Velocity Testing in Clay
(Master thesis, 2015)The soil stiffness at small strains is an important parameter for settlement predictions and for understanding soil behaviour under seismic/dynamic loading. The small strain stiffness is usually found from the shear wave ... -
On the Earth Pressure Coefficient at Rest During Creep
(Master thesis, 2015)Many geotechnical problems requires assumptions regarding the initial stress state in the soil to be made. The earth pressure coefficient at rest, K0, describes the relationship between horizontal and vertical effective ... -
