This paper presents an application of a recently developed methodology for the identification and analysis of flat surfaces affecting rock masses using 3D LiDAR point clouds(Riquelme et al., 2013 submited). The used methodology has been applied to calculate the algebraic equations of the different discontinuities of a rock slope through a methodology based on next three steps: (a) local curvatu...

Neuro-fuzzy inference systems have been used in many areas in civil engineering applications. A stability assessment model for epimetamorphic rock slopes has been developed by using Adaptive Neuro-Fuzzy Inference System (ANFIS) for its capacity of dynamic nonlinear analyses. In the present study the inference system is employed to predict the stability of the slope by choosing bulk density γ, t...

Due to existence of uncertainties in input geometrical properties of fractures, there is not any unique solution for assessing the stability of slopes in jointed rock masses. Therefore, the necessity of applying probabilistic analysis in these cases is inevitable. In this study a probabilistic analysis procedure together with relevant algorithms are developed using Discrete Fracture Network-Dis...

Slope stability is one of the most important topics engineering geology with a background more than 300 years. So far, various assessment techniques have been developed which include range simple evaluations, planar failure, limit state criteria, equilibrium analysis, numerical methods, hybrid and high-order approaches are implemented in two-dimensional (2D) three-dimensional (3D) space. In mea...

Abstract A deterministic model for the factor of safety an idealized rock mass planar mode failure is developed adopting Limit Equilibrium Method (LEM) using Patton’s shear strength criterion and considering practically occurring conditions such as effect tension crack, water filled up in horizontal vertical seismic acceleration, bolt stabilizing force surcharge. In Pseudo-static analysis accel...

Based on the kinematic approach of limit analysis, a full set of upper bound solutions for the stability of homogeneous rock slopes subjected to tension cracks are obtained. The generalized Hoek-Brown failure criterion is employed to describe the non-linear strength envelope of rocks. In this paper, critical failure mechanisms are determined for cracks of known depth but unspecified location, c...
