Abstract
The key issue in rock slope stability analysis is to determine the critical slip surface and minimal slip surface for complex spatial distribution of joints. Based on the stress result by the Numerical Manifold Method (NMM), this paper proposes a search method to track the critical slip surface and the corresponding minimal safety factor. By converting the slope stability to a graph problem on the frame of the NMM, the solution of minimal safety factor can be classified as a shortest path problem, which can be well solved by the Bellman-Ford method, a global shortest path search method. Finally, the proposed method is applied into the slope stability analysis of a rock slope under construction.
