Abstract | This paper focuses on the stability analysis of three-dimensional rectangular trapdoors beneath cohesive-frictional soils via three-dimensional finite element limit analysis (3D FELA). By applying Terzaghi’s superposition method, the average upper bound and lower bound limit analyses are conducted to determine three stability factors: the cohesion factor (Fc), the surcharge factor (Fs), and the unit weight factor (Fr). Additionally, a machine learning technique, specifically genetic expression programming (GEP), is employed to develop explicit predictive equations for each stability factor. The numerical results show excellent performance of the GEP model prediction, with R2 values of 0.991, 0.992, and 0.994 for the cohesion, surcharge, and unit weight stability factors, respectively. A series of equations, figures, and tables were subsequently developed to determine the stability factors of a rectangular trapdoor. The incorporation of modern machine learning techniques with advanced 3D FELA makes this study highly significant for geotechnical engineering practices. |
