Stochastic analysis of rock slope stability considering cracked rock masses

The Finite Element Method (FEM) has been applied to a variety of slope stability problems, including cracked rock masses. In the present study, the generated mesh is imported from FEM software, and the model is analyzed for determining the cracked rocks slope displacement. Furthermore, a computer program is developed for the stochastic analysis of the slope. In the next step, the effect of different configurations of cracks, such as crack length and orientation, on the maximum displacement of the slope is assessed. To the stochastic analysis of the slope, the elastic modulus and possion’s ratio are considered uncertainties variables. The mean and standard deviation of the maximum slope displacement is obtained via Point Estimate Method (PEM). The results show that the length and orientation of the crack have a remarkable effect on the output. Comparing the probability density functions of the maximum displacement indicate that crack length is more effective than orientation in the maximum displacement of the slope.
