Summary:
This paper discusses the study of a plane failure with the Barton-Bandis (BB) shear failure criterion, an empirical relationship used to calculate the shear strength of discontinuous rock masses.
Initially, a reference is made to the key factors, internal and external, that contribute to a plane failure, and details of other failure criteria used for stability analysis of rock slopes.
The Barton-Bandis criterion is then analyzed. In this criterion, the discontinuities are the determining factor for the stability of the slopes, but also the presence or absence of water within them. The same chapter presents a stability analysis using criterion B-B, but also taking into account the system reliability theory and the Monte-Carlo method.
Finally, two examples of a virtual possible plane failure is solved, a slope stability study is made and the conclusions of the paper are presented.
