Abstract: In order to solve problems in design of anchor bars stringing slope strata together,based on the newly proposed approach of stability analysis upon toppling failure,we established a revised mechanical model for anti-inclined layered rock slopes reinforced by anchor bars stringing strata together. Moreover,a limit equilibrium analysis method based on the revised mechanical model was constructed. The new method considers interaction force of un-reinforced strata while ignores the interaction force between reinforced strata. Aiming at an anti-inclined layered slope in South Anhui Province reinforced by anchor bars stringing strata together,we discussed the influence of length,number and reinforcement location of anchor bars on slope stability. Finally,the best reinforcement plan of the slope was obtained.
