| Summary: | Slope stability is a critical factor in open-pit mining operations. To assess slope
stability, the commonly used indicator is the Safety Factor (FoS) to determine slope
strength. However, in software utilizing the Finite Element Method (FEM), the term
Strength Factor (SF) is more frequently encountered. This study aims to compare
FoS and SF in slope stability analysis using numerical modeling based on the Mohr-
Coulomb criterion. The results show a similarity between FoS and SF values in
determining slope stability, where the FoS and SF values at the specified points
tend to be equivalent under disturbed conditions. However, the comparison also
reveals that most FoS and SF values can significantly differ under stress conditions
approaching in situ stress. |
