As carrying on stability analysis of jointed rock slope by the finite element strength reduction,the calculation accuracy is affected by a lot of factors such as yield criterion,rock mechanics parameters,computation net and so on.According to the study of these factors,the analysis results demonstrated that Mohr-Coulomb inscribed circle criteria is a appropriate choice under the associated flow rule;and under the non-associated flow rule,matched DP Mohr-Coulomb criteria is suitable.In ddition,if the former ...
