主　　题：Slope stability Stability charts Mohr-Coulomb failure criterion Hoek-Brown failure criterion 

摘      要：Although stability charts suggested by Hoek and Bray on the basis of Mohr-Coulomb criterion are used for rock slopes,but complete and precise recognition is required for distinguishing cohesive strength and Mohr-Coulomb equivalent internal friction angle for rock *** paper by Lia et al.[6]is the only one that introduced rock slope charts according to Hoek-Brown failure *** this paper,at first,this type of charts is ***,Mohr-Coulomb failure criterion charts[2]are compared and validated with Hoek-Brown failure criterion ones[6].Next,Bishop method utilizing Slide software is compared with Hoek-Brown failure criterion stability *** standard deviation(ASD),root mean square error(RMSE)and variance account for(VAF)were used for the *** to the results,because of high distribution and very low correlation among the comparisons,Hoek-Brown failure criterion charts are not efficient.
