The method assumes a parallel intercolumn force inclination, analogous to Spencer's 2D approach. This paper presents a simplified 3D slope stability analysis method based on limit equilibrium theory. It satisfies overall force and moment equilibrium about the main rotation axis and can be combined with 3D upper‑bound methods to bracket accurate solutions. The method is numerically tractable for many practical problems. Keywords: slope stability analysis, three‑dimensional analysis, limit equilibrium method, upper bound method.
This paper presents a simplified three-dimensional (3D) slope stability analysis method based on the limit equilibrium theory. The assumption involved in this method is of a parallel intercolumn force inclination, similar to Spencer's method in the two-dimensional (2D) area. It allows for the satisfaction of complete overall force equilibrium conditions and the moment equilibrium requirement about the main axis of rotation. The method has been proven to be numerically tractable for many practical problems. By combining this method with the 3D upper bound approaches, it is possible to bracket the accurate solution of a 3D slope stability analysis problem into a small range.Key words: slope stability analysis, three-dimensional analysis, limit equilibrium method, upper bound method.
