![]() Además, se calculó la probabilidad de falla y la función de probabilidad del factor de seguridad para cuñas removibles. En ambos casos se obtuvo el mismo resultado. El algoritmo fue validado contra los resultados de un programa comercial para calcular factores de seguridad en cuñas de roca. Luego, verifica la posición del talud dentro que ese arreglo que se asocia al modo de falla. El algoritmo define de forma sistemática un arreglo de planos. Además, se planteó un algoritmo para identificar los mecanismos de falla, que fue adaptado a una propuesta existente para calcular el factor de seguridad de cuñas de roca de forma explícita. La orientación de las discontinuidades se modeló como una variable aleatoria siguiendo la distribución Fisher, que es rotacionalmente simétrica. En este trabajo se llevan a cabo análisis de confiabilidad de estabilidad de taludes rocosos. Por lo tanto, es necesario caracterizar su variabilidad de forma apropiada con el fin evaluar la estabilidad de los taludes en roca. Estas incluso controlan la geometría de una falla potencial, lo que se conoce como falla con control cinemático.

Finally, we recommend further work on rock wedge reliability assessment involving rotational nonsymmetric distribution. In addition, a proper definition of removable wedges by kinematic analysis is required before computing the factor of safety because many combinations of planes do not lead to unstable wedges, which reduces the probability of failure. Reliability assessment showed the importance of properly characterizing the variability of joint orientation since the concentration highly influences the computed probability of failure. Besides, the probability of failure and the factor of safety probability function of removable wedges were computed for different concentration parameters. The proposed algorithm was validated by comparison against commercial software both yielded the same results. Then it verifies the relative location of the slope orientation on that set-up, which is related to the mode of failure of the rock wedge. The algorithm systematically defines a set-up of joint planes. We developed an algorithm to define the modes of failure based on the orientation of planes, which was articulated within a methodology to compute the factor of safety of rock wedges explicitly. The orientation of discontinuities was modeled as a random variable that follows the rotationally symmetric Fisher distribution. Accordingly, in this work, a reliability assessment of rock wedges' stability was performed by a Monte Carlo simulation. Hence, a proper characterization and description are needed to assess their stability. ![]() ![]() ![]() They even define the geometry of a potential failure, known a kinematically controlled failure. In fractured rock masses, discontinuities control the mechanical response of rock slopes.
