  1. 1. Adapted data collection in field utilizing RMR and the Q-system

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Amanda Olsson; [2024]
    Nyckelord :Rock mass classification; Q-slope; SMR; Slope stability;

    Sammanfattning : The focus on slope stability has increased rapidly in Norway over the last years due to several unwanted landslides. In Norway, the most used method today to classify the rock mass and to determine the required reinforcement, is the Q-system. In addition to that the RMR method is also a commonly used method.

  3. 2. Epidotization as an Effect of Fluid Rock Interaction, Recorded by a Granitoid From Hågadalen, Uppsala

    Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Författare :Linn Barreby; [2022]
    Nyckelord :Fluids; Fluid Transport; Metamorphism; Metasomatism; Saussuritization; Epidote Group; Geology; Bedrock; Fluider; Fluidtransport; Metamorfos; Metasomatism; Saussuritisering; Epidot Gruppen; Geologi; Berggrund;

    Sammanfattning : A common driving mechanism of metamorphic processes, from which secondary mineralizations and structures develop in a protolith, is known to be a change of the immediate P-T environment that a rock resides in. A factor in this process, which is poorly understood, however, is how the presence of metamorphic fluids in a system, influences the alteration of primary igneous rocks. LÄS MER

  4. 3. Grundförstärkning med pålar i berg : I befintlig konstruktion med begränsat utrymme

    Kandidat-uppsats, KTH/Byggteknik och design

    Nyckelord :Steel pipe; steel core pile; waterproofing; pile foundation; down-the-hole DTH drill.;

    Sammanfattning : This study has been done in order to examine which type of pile, pile driving- and waterproofing methodsare most suited for an existing building. A building that will undergo an extensive reinforcement of itsfoundation. LÄS MER

  5. 4. Modellförsök avseende bergspänningars betydelse för spännvidd av valv

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Minna Larsson; Klara Skoog; [2020]
    Nyckelord :arch; arching; span of arch; rock stress; rock reinforcement; rock bolt; valv; valvbildning; spännvidd; bergspänning; bergförstärkning; bergbult;

    Sammanfattning : Tunnels and anthropogenic underground cavities are a very natural part of our everyday modern life. Especially in larger cities such as Stockholm where the infrastructure reaches far above ground level as well as deep below the surface. LÄS MER

  7. 5. Befintlig och framtida infrastruktur i Dennewitz malmkropp : Prognos och rekommendationer

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Johan Winsa; [2020]
    Nyckelord :bergmekanik; geologi; strukturgeologi; skadekartering; Dennewitz; Malmberget; LKAB;

    Sammanfattning : During mining in the Malmberget mine, large amounts of information such as damage mapping, geological mapping, seismic data and stress conditions are stored. All the data that is obtained is stored in several places with different methods, which makes it problematic to use. LÄS MER
