A Robust Solution Procedure for the Rigorous Methods of Slices

Zheng and co‑authors propose a numerically stable algorithm for solving rigorous limit‑equilibrium methods of slices, such as Morgenstern–Price. The paper examines convergence difficulties that arise for complex slip surfaces or low factors of safety and introduces an improved iteration procedure that converges reliably across a wide range of problems. Benchmark examples demonstrate accuracy and robustness compared with existing implementations.
