Where is the scale factor in the Hoek & Brown rock mass failure criterion? Let's imagine an open pit mine in a jointed rock mass, benches could be 10, 15, or 20 meters in height. GSI does not account for the scale and it is among the main inputs for the prediction of these parameters, and D is an ambiguous parameter and there is no guideline to link it to the scale. Should we use the same (m, s, a) values for the stability analyses of these different scenarios? Or is it time to shift toward discontinuum methods, depending on the modes of failure?
Hossein Rafiei Renani, you wrote an interesting paper on the Hoek and Brown failure criterion. I am keen to hear your thoughts.
@Erik Eberhardt,
I found your paper on the Hoek and Brown failure criterion quite interesting (Article The Hoek–Brown Failure Criterion
). I'd like to hear more about your thoughts and insights on this topic.- Badges
