“…Recently, the Hoek-Brown failure criterion (Hoek et al 2002) has been applied to bearing capacity and slope stability by Merifield et al (2006) and Li et al (2008Li et al ( , 2009Li et al ( , 2011 respectively. The latest Hoek-Brown failure criterion for rock masses is expressed as the following equations: (1) where (4) The magnitudes of m b , s and a rely on the geological strength index (GSI), which describes the rock mass quality.…”

Some of the geotechnical parameters used in the analysis may not be accurately measured directly from laboratory tests due to effects of sample disturbance and errors of tests. The back analysis or the observational method are thus often applied to determine the representative and/or dominant strength parameters based on field observations in practice. Based on the Hoek-Brown failure criterion, it was known that the disturbance factor (D) should be determined with caution. The difficulty of measuring rock mass disturbance accurately has been shown. Three rock slope failures will be investigated in this paper using back-analysis technique. In addition, various rock mass strength parameters are taken into consideration.

“…Yang et al (2004a, b) and Yang and Zou (2006), based on the Hoek-Brown criterion, proposed a tangential strength method in an upper bound analysis to obtain the stability factor of rock slopes. Li et al (2008Li et al ( , 2009Li et al ( , 2011 have produced stability charts for rock slopes using the FEM-based upper and lower techniques proposed by Lyamin and Sloan (2002a, b) and Krabbenhoft et al (2005). An obvious drawback with the traditional FEM-based limit analysis approaches being applied to rock slopes is their inability to characterize the behavior of discontinuous rock masses.…”

The authors present a numerical limit analysis on the slope stability in this paper using the rigid finite-element method (RFEM). The novelty of this study is the consideration of the rotational component of the centroid velocity for each element, as well as a generalized overturning failure criterion governing the element rotation. By combining the generalized rotation failure criterion with the Mohr-Coulomb failure criterion, the RFEM-based upper and lower bound limit analysis is formulated as a typical primal and dual linear programming problem and is solved effectively by a primal-dual interior-point method. The proposed formulation and methodology are validated by three classical soil or rock slope stability problems. Numerical results confirm the necessity of considering the rotation mechanism in RFEM-based limit analysis for slope stability in order to achieve realistic predictions.

Onl y an article rendered by Lia et al. in 2008 has represented charts based on Hoek-Brown criterion for rock slopes, however, these charts are not precise and efficient. Because of this problem, a modification is suggested for the mentioned charts in this study. The new charts are calculated according to four methods. Among the methods, one relates to fin ite element method using Phase2 software. The other three methods are Janbu, Bishop and Fellenius that belong to lim it equilibrium method by using Slide software. For each slope angle, the method having high correlation coefficient is selected as the best one. Then, final charts are rendered according to the selected method and its specific equations. Among forty equations, twenty-five ones or 62.5% relate to numerical method and Phase2 software, six ones or 15% belong to Fellenius limit equilibrium, six ones or 15% relate to Bishop limit equilibrium, and three ones or 7.5% belong to Janbu limit equilibrium. In order to validate new charts, slope stability analysis is carried out for several sections of Chadormalu iron ore open pit mine, Iran. The error percentage of new charts in limit equilibrium method using Slide software and in Bishop method for slopes of Chadormalu iron ore mine are rendered and compared. The charts on a basis of Hoek-Brown failure criterion for rock slopes show less than ±4% error. This indicates that these charts are appropriate tools and their safety factor is optimal for rock slopes.Keywords: Stability charts; Rock slopes, Hoek-Brown criterion Diagramy stabilności skalistych zboczy otrzymane w oparciu o warunek wytrzymałości HoekaBrowna znaleźć można jedynie w pracy Lia et al.

Jedna z metod opiera się na metodzie elementów skończonych i wykorzystuje oprogramowanie Phase2. Pozostałe trzy podejścia to metody Janbu,
