...; Bieniawski's RMR System; and Warren's Weak-RMR. The Weak-RMR classification system, and empirical support design procedures proposed by Warren et al., 2018 are explored in more detail with a series of numerical models to test design sensitivities. These numerical models have been set up to evaluate...

... to be considered to assess stability. There are empirical methods that relate rock mass classifications with design parameters like slope angles, open-spans and support, Bieniawski [1], Laubscher [2], Barton [3]. These methods do not require an explicit definition of strength of the rock mass, but when numerical...
