  2. 6. Characterisation of Fractured Rock for Grouting Using Hydrogeological Methods

    Author : Åsa Fransson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydraulic test; specific capacity; grouting; water pressure test; geological mapping; grout take; aperture; penetration length; transmissivity;

    Abstract : Sealing of tunnels by grouting demands knowledge concerning the fractured rock and the grout, followed by an appropriate choice of strategy and equipment. In this thesis, the characterisation of rock is the main issue and, since it addresses the engineering problem of producing a description for grouting, the properties of grout and the grouting procedure need to be considered.

  4. 7. Tribology of hydraulic motor

    Author : Daniel Nilsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : A radial piston hydraulic motor has several components involving sliding or rolling interfaces which may encounter tribological problems. Seizure is one of them and it results in complete stoppage of motion between the relatively moving components and has serious consequences in terms of the operation of a hydraulic motor. READ MORE

  5. 8. Smoothed particle hydrodynamics in hydropower applications : modeling of hydraulic jumps

    Author : Patrick Jonsson; Gustaf Gustafsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : In present thesis, the Lagrangian particle based method Smoothed ParticleHydrodynamics (SPH) is used to model two-dimensional problems associated with hydropower applications such as dam break evolution and hydraulic jumps. In the SPHmethod, the fluid domain is represented by a set of non-connected particles which possess individual material properties such as mass, density, velocity, position and pressure. READ MORE

  6. 9. Hydraulic Conductivity of Saturated Sand-Bentonite mixtures

    Author : Malin Sundsten; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quarry sand; design; bentonite; landfill barrier; field tests; dry density; foundry green sand; laboratory tests; hydraulic conductivity;

    Abstract : The implementation of the EC directive concerning landfill liners and covers sets stricter technical and environmental requirements for landfill barriers. It is therefore essential to identify suitable materials that fulfil these requirements. READ MORE

  7. 10. Hydro-Mechanical Behaviour of a Pressurised Single Fracture: An In-situ Experiment

    Author : Patrik Alm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydro-mechanical behaviour; hydraulic field test; transmissivity; effective stress; aperture; fracture stiffness; fracture; slug test;

    Abstract : Exploration of ground water resources, grouting, disposal of nuclear waste and extraction of geothermal energy are examples of activities which require consideration of the relationship between effective stress and transmissivity. However, this relationship is poorly understood and very few investigations have been conducted in field scale. READ MORE
