  1. 11. Structural and Engineering Geological Investigation of Fracture Zones and Their Effect on Tunnel Construction

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Linda Alfvén; [2015]
    Nyckelord :Fault zone; drill core; tunnel construction; 2D models; Förkastningszon; borrkärna; tunnelbyggnation; 2D-modeller;

    Sammanfattning : This thesis project was conducted in connection with the project, Stockholm’s future sewer pipeline, which is a planned sewer pipe that will run through a tunnel from western to southern Stockholm. This tunnel will pass under Lake Mälaren between Eolshäll and Smedslätten, where there are two faults indicated on the geological map, that could affect the tunnelling and create risks during the construction.

  3. 12. Major Fracture Zones in Fiskarfjärden, Stockholm

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sorin Ignea; [2015]
    Nyckelord :Stockholm Bypass; structural model; major fracture zones; kinematic indicators; Förbifart Stockholm; stora strukturer; stora sprickzoner; kinematiska indikatorer;

    Sammanfattning : This Master thesis is written in connection with the Stockholm Bypass project which is Trafikverkets and Sweden’s largest infrastructure project to date. It will consist of 21 km of motorway running west of Stockholm city linking the southern and the northern parts. LÄS MER

  4. 13. 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

  5. 14. Structural model of the Lambarfjärden area from surface and subsurface data in connection with the E4 Stockholm bypass

    Master-uppsats, Berggrundsgeologi

    Författare :Anna Vass; [2012]
    Nyckelord :Lambarfjärden; sturctural model; fracture; E4 Stockholm Bypass;

    Sammanfattning : The present Master thesis is written in connection with the E4 Stockholm bypass, which is a future motorway linking northern and southern Stockholm, and will mostly run through tunnels. The bypass will cross the Lake Mälaren in the Lambarfjärden area, where a fault is indicated on the geological maps, which would create risks for tunneling. LÄS MER

  7. 15. Remote Sensing and Statistical Analysis of Fracture Populations Around Lake Thingvallavatn, SW Iceland

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Johan Oxenstierna; [2012]
    Nyckelord :;

    Sammanfattning : This study aims at a description and statistical analysis of tectonic and magmatic fractures in the Western Volcanic Zone (WVZ) on Iceland. Two fracture populations are studied with respect to their distance to the Hengill volcano: The southern area is between 0-10 kilometers from the volcano and the northern area is between 16-25 kilometers from the volcano.
