A MECHANICAL MODEL FOR AN INCLINED BEDDING SLOPE BASED ON ELASTIC THEORY

Based on analysis of the force field in an inclined bedding slope, the authors present a mechanical model, in which the slope is treated as a cantilever beam on the elastic foundation. The internal stresses of the beam are calculated under the action of different forces using the elastic theory. The safety coefficient of the beam is then determined according to Mohr-Coulomb criterion. As a result, a critical length of the stable slope is obtained. By comparing results in this paper with the results obtained from the catastrophic theory method, the authors conclude that the method presented in this paper is applicable for such analysis.
