  1. 1. Effekter av packning av finfilter i fyllningsdammar

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anton Jonsson; [2023]
    Nyckelord :Fyllnadsdamm; Finfilter; Packningsgrad;

    Sammanfattning : There are over 10 000 dams in Sweden of various types and sizes. Most of the larger dams were built around 1950-1970 when the Swedish hydropower was expanded. Since then, the knowledge of engineering dam structures has increased and there are new guidelines for how a dam should be built. LÄS MER

  3. 2. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Eduardo Garcia Cañas; [2022]
    Nyckelord :HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

    Sammanfattning : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. LÄS MER

  4. 3. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Axel Barrdahl; [2022]
    Nyckelord :Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

    Sammanfattning : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. LÄS MER

  5. 4. Radio Frequency Energy Harvesting In Embankment Dams

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datorteknik

    Författare :William Järvström; Axel Lundberg; [2022]
    Nyckelord :Energy Harvesting; Embankment Dams; Radio Frequency; Wireless Energy Transfer;

    Sammanfattning : Energy harvesting can be used to consume the potential power of the surrounding environment. This harvesting can be done in different ways, some common energy harvesting modalities are vibrations, heat differences, solar power, and RF energy. LÄS MER

  7. 5. An Overview of State-of-the-art Hydraulic Conductivity Measurements in Coarse Grained Materials

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jakob Andrén; [2021]
    Nyckelord :hydraulic conductivity; permeability; embankment dam; coarse grained; flow regime; hydraulisk konduktivitetsmätning; permeabilitet; fyllnadsdamm; grovkorniga material; flödesregim;

    Sammanfattning : Embankment dams are made from soil materials of varying sizes and widely used all over the world.When constructing these, knowing the hydraulic conductivity (K) of the soil materials is a keyparameter in order to construct safe embankment dams. A knowledge gap regarding K measurementsin coarse grained soils has been identified. LÄS MER
