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

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

    Abstract : 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.

  4. 3. Environmental and technical evaluation of cement reduction and test methods for fibre reinforced shotcrete in tunnels

    University essay from KTH/Betongbyggnad

    Author : Elin Brodd; Lina Östlund; [2022]
    Keywords : Shotcrete; Global Warming Potential; Environmental Product Declaration; Tunnel construction; Fibre reinforcement; Compressive strength; Residual strength; GGBS; Sprutbetong; Klimatpåverkan; Miljövarudeklaration; Tunnelbyggande; Fiberarmering; Tryckhållfasthet; Residualhållfasthet; Granulerad Masugnsslagg;

    Abstract : The dominating support method for hard rock tunnels today is use of fibre reinforced shotcrete in combination with rock bolts. The fibre reinforced shotcrete secures smaller blocks, while rock bolts are used to support larger blocks in the rock. Application of shotcrete is done by spraying against the rock surface using compressed air. READ MORE

  5. 4. EVALUATION OF ENVIRONMENTAL AND TECHNICAL PERFORMANCE OF ALTERNATE FIBRES FOR SHOTCRETE IN TUNNELS

    University essay from KTH/Betongbyggnad

    Author : Shilpa Anand; [2022]
    Keywords : Shotcrete; Life cycle assessment; Environmental Product Declaration; Global warming potential; steel; basalt and synthetic fibres; flexural strength; energy absorption.;

    Abstract : Tunnels in hard and jointed rock are normally excavated in an arch shape to enable the rock mass to support its weight. Since the beginning of the 1980's, fibre reinforced shotcrete (FRS) in combination with rock bolts have been the dominating support method for hard rock tunnels. READ MORE
