A numerical investigation of strain-softening in soft clay for a modelled shear vane
(Master thesis, 2018)The strain-softening phenomenon has been extensively studied the last decades in context of numerical modelling and progressive failure mechanism. In this study, a vane is modelled in soft clay with a negative dilatancy. ... -
A study of the Dynamic Properties of Quick Clay from Flotten NGTS - with Particular Interest in Anisotropy and Stress Relief During Unloading
(Master thesis, 2018)The stiffness of a soil is of great importance in many areas of geotechnical engineering. It forms the link between strain and stress, which is crucial in incremental numerical modelling. More specific to this study, the ... -
Advanced Probabilistic Slope Stability Analysis on Rissa Slope
(Master thesis, 2016)Probabilistic analysis is powerful in investigating the influence of uncertainties on a given geotechnical problem. The way to conduct an uncertainty quantification in geotechnical engineering is shown in a particular case ... -
An Experimental Investigation of Pore Pressure Generation in Moving Debris
(Master thesis, 2016)Debris flow is a typical type of landslide and has huge impact on human life. The moving debris in traditional numerical modeling is assumed as hydrostatic along the flow depth, which is not the actual case when the ... -
Back calculation of Debris flow Run-Out & Entrainment Using the Voellmy Rheology
(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 ... -
Bearing Capacity Analysis Over Mudmat Foundations Under Multidimensional Loading
(Master thesis, 2018)The ultimate bearing capacity is at its maximum when the foundation is under pure vertical loading. In the field, pure vertical loading is the least likely load combination to happen but, it is mostly combined loading ... -
Correlation between SPT and CPT
(Master thesis, 2014)The objectives of this thesis are to introduce and describe SPT, CPT methods and the correlation between them. Moreover, it is explained how the correlation between SPT and CPT is reliable and what kinds of studies are ... -
Deformation Analysis of Soft Soils - Case Study of South Ring Road of Gdansk
(Master thesis, 2018)Nowadays, a significant part of geotechnical analyses refers to settlement problem, due to its impact on designed constructions. The problem is more noticeable when displacements are large, what usually takes places when ... -
Detection of Landslides - Using Optical Satellite Remote Sensing
(Master thesis, 2018)Norway is exposed to frequent landslide activity. A large number of landslides occur in Norway each year, causing damage to infrastructure, or even loss of lives. Due to the changing climate and more extreme weather patterns, ... -
Earthquake Response Analysis of Pile Supported Structures - Correspondence of PLAXIS 2D with Eurocode 8
(Master thesis, 2017)Earthquake response of a structure on relatively soft soil is influenced by the soil material properties and type of foundation i.e. shallow or deep foundation. The design recommendations of Eurocode 8 provide a conservative ... -
Earthquake Response of Different Types of Retaining Walls
(Master thesis, 2016)Retaining walls are designed to restrain against the lateral earth thrust while keeping its original position intact. During an earthquake, the lateral earth thrust increases and the walls become susceptible to failure ... -
Effect of Testing Temperature on Stiffness, Strength and Apparent Sample Disturbance in Quick Clay Samples from NGTS Quick Clay Site Flotten
(Master thesis, 2018)The effect of temperature on laboratory measurements of soil strength and stiffness has occasionally been revisited as a research topic since the 1960 s. Previous studies indicate that both preconsolidation pressure and ... -
Entrainment of Bed Sediments by Debris Flow
(Master thesis, 2016)Debris flows have proved to be a major worldwide hazard for more than 100 years owing to the destruction of lives, property and infrastructures. This occurrence of debris flows is likely to increase in the future due to ... -
Et Laboratoriestudie på Hviletrykkskoeffisientens Utvikling under Kryp for både Uforstyrret og Omrørt, Rekonsolidert Tillerleire
(Master thesis, 2016)For å løse mange geotekniske problemer er det nødvendig med antagelser om hvilke initielle spenningstilstander jorden er påvirket av. Forholdet mellom horisontal og vertikal effektiv spenning beskrives med jordtrykkskoeffisienten ... -
Finite Element Analysis of Coupled Thermo-Hydro-Mechanical Processes in Fully Saturated, Partially Frozen Soils
(Master thesis, 2017)Interest in permafrost, or seasonally frozen ground, has been increasing over the last decades. Nearly 24% of the northern hemisphere, is covered with permafrost. Humankind's need for energy and raw materials has pushed ... -
Flow Behaviour of Fine-Grained Soils
