Implication

This analysis reveals discrepancies in safety factors for drained and undrained methods in slope evaluation, suggesting improvements for accurate assessments.

Key Points

The proposed framework aims to reconcile drained and undrained analysis for better slope stability assessment.
Undrained analysis often leads to lower safety factors, influencing design choices and potentially making them overly conservative.
The study identifies key factors contributing to safety overestimation and presents numerical studies to enhance method coherence.
Recommendations for formulation of safety requirements can improve the reliability and practicality of slope stability evaluations.
