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

    Uppsats för yrkesexamina på avancerad nivå, KTH/Byggvetenskap

    Författare :Emil Andersson; [2019]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. CPT-sondering och trycksondering, en jämförande studie om utvärdering av friktionsvinkel i friktionsjord

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Adam Bolinder; [2017]
    Nyckelord :Friction; friction angle; CPT; pressure probe; correlation; Friktion; friktionsvinkel; CPT-sondering; trycksondering; korrelation;

    Sammanfattning : Knowledge of the soils friction angle is necessary to avoid landslides at slope stability surveys and dimensioning for foundation of different constructions. Frictional forces mainly builds up friction soil and the friction angle is defined by the angle when landslides occur. Friction angle can be evaluated using CPT or pressure probe. LÄS MER

  5. 4. A systematic review of biomechanical factors in runners before, during and after Iliotibial Band Syndrome

    Magister-uppsats, Gymnastik- och idrottshögskolan, GIH/Institutionen för idrotts- och hälsovetenskap

    Författare :Hanna Rautiainen; [2015]
    Nyckelord :;

    Sammanfattning : Aim The aim of this study was to define functional tests, and to describe kinematic and kinetic factors as well as muscular function, and to study any differences in these parameters, found in the literature, between runners before developing, during and after recovering from ITBS compared to healthy controls. Method A systematic literature review was performed in Cinahl, EMBASE, PEDro, PubMed and Swemed + with the search terms: "Iliotibial band syndrome", "Iliotibial band friction syndrome" and "Iliotibial tract syndrome".

  7. 5. Controlling parameters for normal and shear behaviour of rock fractures-a study of direct shear test data from SKB

    Uppsats för yrkesexamina på avancerad nivå, KTH/Jord- och bergmekanik

    Författare :Hanna Melin; [2012]
    Nyckelord :open fracture; shear strength; mechanical parameters; friction angle; roughness;

    Sammanfattning : The deep mining and civil engineering industry need to perform rock stability analyses during excavation projects. The stability is mainly controlled by the shear strength of the rock fractures, which are the weakest point of the rock mass. In turn, the shear strength is governed by the mechanical properties of the fractures. LÄS MER
