NettetHowever, rock slope stability charts based on the Generalized Hoek–Brown (GHB) criterion, which is one of the most widely adopted failure criteria to estimate rock mass strength in rock engineering, are considerably limited. This paper presents new stability charts for the analysis of rock mass slopes satisfying with the GHB criterion. NettetGSI chart should not be used for input into the Hoek-Brown criterion as shown in Figure 1.
