A Comparison of Railway Load Models for Geotechnical Analysis
(Master thesis, 2018)Bane NOR is responsible for developing the railway network in Norway. In Norway, the Eurocodes are specifying how structural design in general should be conducted. This also applies to the railways. To guide those responsible ... -
A Laboratory Study of Salt Diffusion and its Effect on Electrical Resistivity and Sensitivity in Quick Clay
(Master thesis, 2016)Resistivity measurements as a geophysical method have become increasingly popular as a supplement to geotechnical field investigations over the last years. The main use for this method is to uncover the possibility of quick ... -
A Study of the Strength and the Physical Properties of Glacier-ice Runways - Assesment of Troll Airfield, Antarctica
(Master thesis, 2018)Airfields located in Antarctica are unique because the runways are constructed by glacier ice. Ice as a construction material differs from conventional runway materials in sense of strength, hardness and temperature ... -
An Experimental Study of Thermal Properties of Permafrost Soils
(Master thesis, 2018)Soil is a multiphase porous media, and its complexity increases when the soil freezes. The high compressive strength of frozen soil has been utilized by geotechnical engineers in construction of frozen earth structures. ... -
An experimental study of unfrozen water content in fine grained permafrost soils
(Master thesis, 2017)The strength of a soil increases when the ground freezes, but some of the water will remain unfrozen. Unfrozen water content is an important thermal property of a soil as flowing water may supply heat, reduce the strength, ... -
Behaviour of piles in clay subjected to cyclic lateral loading
(Master thesis, 2018)In order to make offshore wind turbines more cost-efficient and competitive in international energy markets, design methods must be improved to reduce uncertainties in load and soil modelling. The current method of modelling ... -
Betydning av spenningsnivå under herding av kalksementstabilisert leire. - Effekter på fasthet og stivhet.
(Master thesis, 2018)Kalk-/sementstabilisering er en mye brukt metode i Norge for stabilisering av sensitiv leire. Ved å blande inn kalk og sement i leiren økes dens fasthet, og stabilitet og bæreevne forbedres. Forsøk utført på kalksementstabilisert ... -
Correlation of Properties in Geotechnical Engineering - The impact of Index parameters on Mechanical Properties of Soil
(Master thesis, 2018)In order to effectively use the mechanical parameters of a soil as a tool in soil mechanics, insight about basic properties is necessary. Index properties of soil, such as the water content and the plasticity index influence ... -
Cyclic Behaviour of Water Saturated Dense Sand
(Master thesis, 2017)Several monotonic and cyclic triaxial tests have been performed at NGI in association with the ongoing strategic project, SP9. The test material is dense saturated sand from the Siri offshore field in the North Sea, and ... -
Earthquake Soil-Structure Interaction Analyses of Offshore Sub-Sea Structures Founded on Closed Caisson Foundations
(Master thesis, 2018)One of the most challenging issues in the design of sub-sea structures founded on closed caisson foundations is their structural response to dynamic loading. Currently, the foundation design is mostly based on fully ... -
Effect of Anisotropy, Strain Rate and Progressive Failure in Numerical Simulations of the Shear Vane Test
(Master thesis, 2017)The shear vane test is a method of determining the in-situ undrained strength and remolded shear strength of cohesive soils. During the shear vane test, an increasing torque is applied until the surrounding soil goes to ... -
Effect of initially inclined principle stress directions on undrained shear strength for anisotropic clay
(Master thesis, 2017)In this thesis is a continuation of Rabstad's and Isachsen's work on the user-defined soil model ADPXX is done. The model aims to include initially consolidated shear stressesin the yield criterion for anisotropic clays, ... -
Effect of Temperature on Measured Strength Parameters from Variations in Both Storage and Testing Temperatures
(Master thesis, 2017)The effect of temperature on laboratory tested mechanical properties of clay has been debated for many years. The fact that soil parameters are affected by variations in temperature is generally agreed upon, resulting in ... -
Effekt av lagringstid for 54 mm sylinderprøver av leire fra Tiller
(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 ... -
Effekten av statiske og sykliske laster på gyste bergstag
(Master thesis, 2017)I forbindelse med forankring av brukonstruksjoner i berg, er gyste bergstag sett på som et alternativ. For å forstå nedbrytningen av bergstag under sykliske og statiske laster bedre, er det i denne oppgaven utført et ... -
Evaluation of unwanted drilling effects: In-situ measurements compared to finite element simulations
(Master thesis, 2017)In the latter years, there has been an increasing interest in unwanted settlements and damages occurring on neighboring infrastructure due to foundation work. There has been a research project going from 2012 to 2015 ... -
Fengselstomta - en naturlig skråning med marginal sikkerhet - Vesentlig forbedring med topografiske stabiliseringstiltak
(Master thesis, 2017)Tema for denne masteroppgaven er skråningsstabilitet, med utgangspunkt i skråningen fra Fengselstomta ned til Nidelva ved Studentersamfundet i Trondheim kommune. Funn av dyptliggende kvikkleire på Fengselstomten øst for ... -
Field and Laboratory Investigations to Evaluate the Coefficient of Earth Pressure at Rest - NGTS Flotten Quick Clay Test Site
(Master thesis, 2017)The coefficient of earth pressure at rest is a key geotechnical parameter, required in almost any investigation of material behaviour. A review of literature on the in situ and laboratory determination of K0' has been ... -
