Stability Analysis of Reverse-Dipping Rock Slopes Based on the Bi-Directional Evolutionary Structural Optimization Method (BESO) Prediction Method

Year: 2026

Type: article

Abstract: Sliding failure is a common form of instability for reverse rock slopes. The determination of the failure plane for such unstable slopes is currently a key and challenging issue in research. To pinpoint the position of the failure surface with higher accuracy, this paper proposes a key equilibrium model based on the symmetric bidirectional evolutionary structural optimization (BESO) method. This model is based on the basic parameters of the slope, the BESO method, and the limit equilibrium theory. It uses its own algorithm program to search and determine the key failure plane of the slope. At the same time, two rock slope model tests were conducted to verify the effectiveness of this method in slope stability analysis. The calculated results exhibit a good consistency with the experimental outcomes, which confirms the feasibility of using the key equilibrium-bidirectional evolutionary structural optimization (CE-BESO) method for stability evaluation of this type of slopes.
