A Global Procedure for Evaluating Stability of Three-Dimensional Slopes

Sun, Zheng and Jiang propose a global 3D limit-equilibrium optimisation procedure that satisfies all equilibrium conditions without assuming interslice/intercolumn force functions. The method bounds the factor of safety using optimisation techniques and avoids numerical challenges typical of 3D column-based approaches. Examples show narrow safety-factor intervals even for complex failure surfaces.
