  1. 6. Reliability – based analysis of embankment dams

    University essay from KTH/Jord- och bergmekanik

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

    Abstract : 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. READ MORE

  3. 7. Evaluation of long-term performance of sodium silicate grouted in embankment dams

    University essay from KTH/Jord- och bergmekanik

    Author : Jenny Fu; [2019]
    Keywords : Sodium silicate; water glass; embankment dams; remedial grouting; dam monitoring;

    Abstract : Embankment dams is the most common type of dams in operation inSweden today. Due to the nature of embankment dams, seepage throughthem will always occur. If the seepage velocity exceeds a critical velocity,internal erosion is initiated, which could lead to damage in form of pipingand sinkholes. READ MORE

  4. 8. Experimental Assessment of Contact Erosion in Embankment Dams with Glacial Till Core

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Chinmoy Pattanaik; [2018]
    Keywords : ;

    Abstract : Contact erosion is a type of  internal erosion which develops at the boundary between two varying soil layers inside a dam body under the condition of tangential water flow inside the coarser soil parallel to the boundary. As the behaviour of foundation is unknown as the grout curtain starts eroding after a couple of years. READ MORE

  5. 9. Resistivity and Seismic Characterization of an Embankment Dam. A Case Study in Northern Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Álvaro Polín-Tornero; [2018]
    Keywords : embankment dam; Sweden; ERT; seismic refraction; seismic reflection; modelling; jordfyllningsdamm; Sverige; ERT; seismisk refraktion; seismisk reflektion; modellering;

    Abstract : The main cause of failure in embankment dams - which represent 75% of all dams in the world (ICOLD, 2018) - is the internal erosion produced by excessive seepage not accounted for in their designs. This erosion can cause that a small anomalous structure, not likely to be considered as risky, turns rapidly into a significant structural damage if not recognized on time. READ MORE

  6. 10. Feasibility study of dam deformation monitoring in northern Sweden using Sentinel1 SAR interferometry

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Cecilia Borghero; [2018]
    Keywords : SAR interferometry; Sentinel-1A; dam deformation monitoring;

    Abstract : Dams are man-made structures that in order to keep functioning and to be considered structurally healthy need constant monitoring. Assessing the deformation of dams can be time consuming and economically costly. READ MORE
