Integrating gray system analysis and empirical method for slope stability assessment in road engineering

The study aims to improve the prediction of slope stability in road engineering by combining sophisticated analytical methods, including ABAQUS software-based finite element modeling and gray relational analysis. The aim is to devise a systematic and impartial strategy that reduces the subjective biases linked with conventional empirical techniques, enhancing the precision of safety factor computations for soil slopes across diverse geological and environmental scenarios. This strategy tackles the drawbacks of traditional approaches, which frequently rely on empirical procedures and produce inconsistent findings in various contexts. The methodology entails utilizing ABAQUS software to create a numerical slope model and then calculating safety factors under different operating situations using the finite element strength reduction method. The improved gray relational analysis captures the complexity related to slope stability and offers a more thorough knowledge of variable interdependencies. The study uses ABAQUS to model slope stability problems and, despite its complexity, calculates exact safety factors using the finite element strength reduction approach to assess slope performance under various scenarios. The paper illustrates how the suggested approach may be used practically in engineering projects and how it can enhance the procedures involved in making decisions about slope stability evaluations.
