Stability analysis of undrained anisotropic slopes has been made by a semi-analytical approach. The variational calculus is employed to find the critical sliding surface and the extremized resistance functional for general undrained anisotropic materials in seismic condition. A complete set of formulation with the solution is presented. In this approach, no failure surface is assumed and it is obtained throughout the solution procedure. The semi-analytical solution highly increases the efficiency of the computational effort and the accuracy of the results. The stability factor is reported for a series of anisotropic slopes in undrained condition subject to a range of pseudo-static earthquake accelerations. Finally, the results are interpreted and discussed by AI to make a comparison between a manual and an AI-assisted interpretations.
