Influence of Fracture Geometric Characteristics on Fractured Rock Slope Stability

Analysis of the stability slopes in fractured rock masses is not trivial and fraught with uncertainty risk. A DFN-DEC model (Discrete Fracture Network-Distinct Element Code) based on MATLAB platform developed to evaluate random fractures. Then, influences mean values geometric characteristics (i.e., trace length T, dip D, spacing S) for both horizontal (denoted 1) inclined 2) fractures slope are investigated. The results indicate that proposed adequate, robust, can generate more realistic fracture networks. By means probabilistic analysis Monte Carlo simulation), we obtain a accurate assessment result slopes. In addition, it found μFs (the Fs) decreases increase μT1, μT2 fractures, respectively) μD1 fractures), increases gradually μD2 μS1 μS2 respectively). Furthermore, related have much greater influence μFS than This study be well applied engineering practice, e.g., preliminary evaluation according statistics characteristics.
