Abstract: The stability of rock massifs (both continuous natural, and disjointed artificial ones) is largely determined by their internal structure and the mutual arrangement of internal elements (layers, cracks or rock pieces). To describe the stress-strain state of a solid rock massif, the finite element method (FEM) has proven itself well. For solving such problems as applied to disperse media, the discrete element method (FEM) is more optimal. In this case, a solid massif can be anisotropic - layered and fractured, with different bedding elements and strength parameters of the layers and joint systems. The dispersed technogenic massif can be represented by particles of various shapes and sizes with different parameters of contacts between ones. Prediction of the rock massifs using FEM, DEM and their combination has recently become more widely used because of the good agreement with the results of field tests. The article provides an overview of innovative methods for modeling various rock massifs to determine their strength parameters and assess stability.
