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

    University essay from Luleå tekniska universitet/Geoteknologi

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

    Abstract : 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. READ MORE

    Abstract : Vid konstruktion av bullerskärmar så väljs vanligtvis pålning som grundläggningstyp. Det finns flera modeller som kan approximera ett krav på minsta pållängd beroende på olika typer jordförhållande och vindlast. READ MORE

  4. 3. Evaluation of influence from matedness on the peak shear strength of natural rock joints

    University essay from KTH/Byggvetenskap

    Author : Emil Andersson; [2019]
    Keywords : Rock joints; Peak shear strength; Matedness; Casagrande et al. criterion; Peak friction angle; Shear strength; Bergssprickor; Maximal skjuvhållfasthet; Passning; Casagrande et al. kriterium; Friktionsvinkel; Skjuvhållfasthet;

    Abstract : In Sweden, the rock mass is commonly used for construction of tunnels and caverns. The rockmass is also used as a foundation for large structures such as bridge abutments and dams. Forthese structures, the understanding of the rock mechanical properties play a key role for reachingan acceptable safety level and minimizing cost. READ MORE

  5. 4. Progressive failure research on foundation surface of the Longtan gravity dam

    University essay from Institutionen för geovetenskaper

    Author : Dag Wästlund; [2011]
    Keywords : Dam safety; SRF-method; Sliding failure of gravity dams; Longtan dam; Safety reserve coefficients; Progressive failure of dam foundation; Dammsäkerhet; SRF-metoden; Glidning av dammfundament; Longtan dammen; Säkerhetsreservkoefficienter; Progressiv felanalys av dammfundament;

    Abstract : The most common failure of concrete gravity dams is sliding along the foundation surface. This thesis studies progressive failure of the Longtan dam on the upper Hongshuie river in china.Two methods are used in this thesis; the Safety Reserve Factor (SRF) method and the Overload method.
