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.
