  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.

  5. 4. Rock Wedge Stability Assessment : A Comparative Analysis of Limit Equilibrium and Discrete Element Methods

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

    Author : Vilma Nordh; [2024]
    Keywords : Numerical modelling; wedge stability; 3DEC; UnWedge;

    Abstract : Rock wedge stability is a common concern in underground excavations. Since the wedge stability influences the support design, it is important to use a wedge stability analysis method that can capture factors like excavation geometry, joint parameters and properties, rock mass properties, rock cover, and stress field as accurately as possible.
