Slope (slope stability analysis) ← Knowledge Base Can you model retaining walls in Slope? In the Analysis Method table, which Method of Analysis should I use? In the Analysis Method dialog, which Factor of Safety should I use? How do you model an artesian water basin or perched water table in Slope? Does Slope consider the Morgenstern-Price or Spencer's methods for both force and moment equilibrium? Why does applying a soil nail force as a surface load obtain a different Factor of Safety?
