  1. 1. Timber pile-supported road embankment : Numerical and analytical analysis of field monitoring project E4 Råneå

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

    Författare :Kent Nystedt; [2022]
    Nyckelord :Geosynthetic reinforcement; Geosynthetic reinforced pile supported embankment; Pile distance; Embankment height; Finite element method; Pile efficacy;

    Sammanfattning : The previous E4 Råneå road embankment was prone to flooding. Risk of flooding in combination with settlements of the road due to the weak underlying sulphide soil was problematic. The Swedish Transportation Administration improved the length section E4 Råneå by rebuilding the road using the method light embankment piling. LÄS MER

  3. 2. 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

  4. 3. Stabiliserade/solidifierade muddermassor bakom spont i en marin miljö

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Fredrik Bergman; Christian Ramel; [2021]
    Nyckelord :S S; stabilization; solidification; ex-situ mass stabilization; dredged material; contaminated; stress path; consolidation stress; binder; earth pressure; sheet pile; quay; water; Gävle Harbor and Oxelösund; S S; stabilisering; solidifiering; processtabilisering; muddermassor; förorenade; spänningsväg; konsolideringstryck; bindemedel; jordtryck; spont; hamn; vatten; Gävle Hamn och Oxelösund;

    Sammanfattning : Vid utvidgning av befintliga hamnar kan den relativt nya metoden stabiliserade/solidifierade (S/S) förorenade muddermassor användas i anslutning till spont. S/S metoden används för att binda föroreningarna fysikaliskt eller stänga in dem samt för att förbättra massornas hållfasthets- och deformationsegenskaper. LÄS MER

  5. 4. Hydro-securitization in the Indus River basin: An analysis of Indo-Pakistani security frames

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Vidar Wirén Gimle; [2019]
    Nyckelord :Securitization theory; India-Pakistan; Hydropolitics; Security frames; Transboundary waters; Law and Political Science;

    Sammanfattning : The animosities between India and Pakistan have been continuous since partition of British India over seven decades ago. Disputes over Kashmir and the rivers flowing through the region can be said to represent a nucleus of the tensions between the two countries. LÄS MER

  7. 5. Settlement calculation for lime/cement column improved clay : Analytical and numerical analyses related to a case study

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Hulumtaye Kefyalew Yederulh; [2018]
    Nyckelord :LCC; deep mixing; consolidation settlement; rate of consolidation; numerical analysis; analytical analysis; field measurement.; KC-pelare; djupstabilisering; konsolideringssättningar; konsolideringsgrad; numerisk analys; analytisk analys; fältmätningar;

    Sammanfattning : The dry deep mixing method is widely used to improve a soft clay soil to increase the shear strength as well as to reduce the time for consolidation. It is a mechanical mixing process that makes parts of the soil stiffer than its original strength. It is mainly applicable to soft clay or peat soil. LÄS MER
