  1. 1. Development of grout for deep shaft

    University essay from KTH/Byggteknik och design

    Author : Karl Lindberg; Adam von Krusenstierna; [2021]
    Keywords : Rock injection; Grout; Shaft; Laboration; Cement; Cement mixture; Bergsinjektering; Injekteringsbruk; Schakt; Laboration; Cement; Cementblandning;

    Abstract : In tunnel engineering one of the most important factors are the groundwater flow. To solve this problem a method called grouting is commonly used. In this study grout mixes are developed based on specific requirements for a deep shaft located next to a body of water. READ MORE

  2. 2. Grouting Design Considering Different Geological Conditions : Grout evaluation for the extension of the Blue Metro Line

    University essay from KTH/Jord- och bergmekanik

    Author : Roaa Al Omari; Yasmeen Alali; [2021]
    Keywords : ;

    Abstract : This thesis forms the basis for a new documented experience of grouting design and work in the extension of the blue metro line in Stockholm. It includes documentation of the grouting design based on theoretical basis, stop criteria and fan geometries for favorable and unfavorable geological conditions. READ MORE

  3. 3. Major and trace element geochemical analysis of norites in the Hakefjorden Complex to constrain magma source and magma plumbing systems

    University essay from Lunds universitet/Geologiska institutionen

    Author : Aodhan Barrett; [2020]
    Keywords : Anorthosite; norite; Plagioclase; Hakefjorden Complex; Sweden; Trace Elements; Geochemistry; Magma Origin; Earth and Environmental Sciences;

    Abstract : Major and trace element data taken from plagioclase crystals from anorthosites and related rock units in the Hakefjorden Complex located off the west coast of Sweden were investigated for the purposes of constraining magma chamber processes and the source of the magma. Although the anorthosite units were completely homogenous in regards to its chemistry, the plagioclase in the associated norite and ilmenite-leuconorite units showed substantial variation. READ MORE

  4. 4. Flow Paths in the Húsmúli Reinjection Zone, Iceland

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Sigrún Tómasdóttir; [2018]
    Keywords : Húsmúli; Hellisheiði Power Plant; geothermal reinjection; tracer tests; numerical modeling; Húsmúli; Hellisheiði kraftverk; geotermisk injektion; spårtest; numerisk modellering;

    Abstract : Reinjection of spent geothermal fluids has become common practise in geothermal power plants. Reinjection can, despite being mostly beneficial, have unwanted effects such as cooling of nearby production wells and injection-induced earthquakes. READ MORE

  5. 5. Evaluation of "GIN method" at Two fans of City banan project in Stockholm

    University essay from KTH/Jord- och bergmekanik

    Author : Mehran Neshati Sani; [2015]
    Keywords : grouting; GIN method; cement; jacking; penetration; pressure; volume intake;

    Abstract : An underground installation with too much inflow can lead to dangerous consequences for around environment, therefore a well-sealed construction results in appropriate inflows. To mitigate movement of ground water table in underground constructions, it is necessary to seal the rock mass by grout injection. READ MORE
