Three cases were considered in the context of the limit state design philosophy prescribed by Eurocode 7. Three cases are considered to explore the effect of factoring shear strength, surcharge loads, unit weight, and reinforcement loads is explored. The principles, however, apply to all codes that adopt a limit state design philosophy. The purpose of this example is to demonstrate how to conduct a stability analysis in accordance with one particular implementation of the limit state design philosophy: Eurocode 7 (Orr and Farrell, 1999 Bond and Harris, 2008). The calculated Factor of Safety (FS), which is interpreted as an over-design factor, must be greater than or equal to 1.0 for the design to be deemed safe. The stability analysis is completed with partial factors applied to characteristic loads and soil strength parameters. ![]() SLOPE/W can be used to complete a stability analysis with the objective being to check an ultimate limit state in accordance with various limit state design approaches such as Eurocode 7, Norwegian Standard NS 3480, and British Standard 8006.
