  1. 1. Estimating the probability of levee failure for flood risk mapping : An application to Paglia River

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Theodora Neromylioti; [2020]
    Nyckelord :Levee failure; inner erosion; piping; backward erosion; seepage; probability of failure; fragility curves; time-dependent failure; hydraulic modelling; flood risk; flood inundation; HEC-RAS;

    Sammanfattning : Climate change results to more extreme and frequent flood events that induce extra risk to flood protection structures such as levees. Thus, estimation of the probability of levee failure is of utmost importance when it comes to structural safety and flood risk assessment. LÄS MER

  2. 2. Reliability – based analysis of embankment dams

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Xiaochen Liu; [2019]
    Nyckelord :Embankment dams; reliability-based analysis; slope stability analysis; internal erosion; dam safety; fyllningsdammar; tillförlitlighetsbaserad analys; analys av släntstabilitet; inre erosion; dammsäkerhet;

    Sammanfattning : Embankment dams are widely used as water-retaining structures through the world. Two principal structural failure modes of embankment dams are internal erosion and slope instability. The objective of this thesis is to investigate the feasibility of applying probabilistic methods in embankment dam assessment. LÄS MER

  3. 3. Jämförelse av beräkningsprogrammen Novapoint Geosuite Stability och Geoslope SLOPE/W med avseende på släntstabilitet

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jonas Hagerfors; [2019]
    Nyckelord :Geoslope SLOPE W; Novapoint GeoSuite Stability; shear strength; Limit Equilibrium; Geoslope SLOPE W; Novapoint GeoSuite Stability; skjuvhållfasthet; Limit Equilibrium;

    Sammanfattning : This thesis deals with the difference between two calculation programs for slope stability, namely Geoslope SLOPE/W and Novapoint GeoSuite Stability. The purpose of the thesis is to compare the two calculation programs with regard to the analysis of slope stability, as well as the two programs' handling of data. LÄS MER

  4. 4. Slope Stability Evaluation from a RiskManagement Perspective : Case Study: the Slussen project in Stockholm

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Louise Larsson; [2018]
    Nyckelord :Slope stability; shear strength; uncertainties; risk management; Släntstabilitet; Skjuvhållfasthet; riskhantering; osäkerheter;

    Sammanfattning : Site characterization and the subsequent determination of soil strengthparameters constitute a significant part of slope stability assessment.Geotechnical engineering is always governed by great uncertainties sincethe soil properties are challenging to estimate for a large soil volume.

  5. 5. Jämförelse av odränerad skjuvhållfasthet mellan CPT-sondering och fallkonförsök på Uppsalalera

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Axel Svensson; [2017]
    Nyckelord :Shear strength; Cone penetration-test; drop cone test; Fallkonförsök; CPT-sondering; skjuvhållfasthet;

    Sammanfattning : The knowledge about the shear strength of a soil is important because it is a key parameter that is used in many calculations in construction engineering. Some examples of what’s possible to calculate are slope stability, the soil pressure against retaining walls and the carrying capacity of building foundations. LÄS MER
