Slope – In the ‘Analysis Method’ dialog, which ‘Factor of Safety’ should I use?
In the ‘Analysis Method’ dialog you can select how you would like the calculated factor of safety to be applied.
- ‘Shear Strength’ will apply to the soil strength
- ‘Disturbing surface loads’ will multiply the loads by the FoS to cause failure, representing bearing capacity problems
- ‘Restoring surface loads’ can be used to determine the required reinforcement.
For more details, please see Section 3.3.3 of the Slope Manual.
