Study on the mechanisms of flexural toppling failure in anti-inclined rock slopes using numerical and limit equilibrium models
TL;DR: In this article, a new UDEC Trigon approach for simulating FTF of a model slope was presented, and a limit equilibrium method, which can reflect the effects of the joint cohesion, was proposed to quantitatively evaluate the stability of anti-inclined rock slopes against FTF.

Stability analysis of rock slopes against sliding or flexural-toppling failure
TL;DR: In this paper, a theoretical model for rock slopes with a potential for sliding or flexural-toppling failure on the basis of two physical model tests is proposed, and a comparative analysis is carried out using the discrete element method and the Aydan et al method with the aim to verify the validity and accuracy of the proposed approach.

Stability analysis of anti-dip bedding rock slopes locally reinforced by rock bolts
TL;DR: In this article, a mechanical model based on limit equilibrium theory is proposed to predict the stability of anti-dip bedding rock slopes locally reinforced by rock bolts, and the proposed model is subsequently verified by comparing its results with numerical results using a discrete element method.

A new method of assessing the stability of anti-dip bedding rock slopes subjected to earthquake
TL;DR: In this paper, the authors proposed a new method considering the inertial force of earthquakes to assess the stability of anti-dip bedding rock slopes (ABRSs) by using the limit equilibrium method and genetic algorithm.

Estimating the geological strength index and disturbance factor in the Hoek–Brown criterion using the acoustic wave velocity in the rock mass
TL;DR: In this article , an improved Hoek-Brown failure criterion was proposed to estimate the disturbance factor and the GSI of a rock mass. But the method is only applicable to very broken rock masses, i.e. having low Cp values.
