- •
A probabilistic simulation-based approach is proposed for reliability analysis of slope stability based on both LEM and FEM.
- •
The computational efficiency is significantly improved at small probability levels.
- •
The proposed approach provides estimates of slope failure probability consistent with that from FEM-based direct MCS.
- •
The approach is illustrated using two slope examples considering spatial variability.
