Design Standard

The Design Standard tab in the Project Settings dialog gives you the option of applying a geotechnical engineering standard to your RocSlope2 model. The available Design Standardoptions are:

• None
• Eurocode 7, Design Approach 1, Combination 1
• Eurocode 7, Design Approach 1, Combination 2
• Eurocode 7, Design Approach 2
• Eurocode 7, Design Approach 3

Eurocode 7

Eurocode 7 is a design document that establishes rules and standards for geotechnical engineering design across Europe (BSI, 2004). Eurocode 7 represents a major change in design philosophy. Traditionally a single, lumped Factor of Safety accounts for all of the uncertainties in the problem. With Eurocode 7, partial Factors of Safety are applied to different components of the analysis. The partial factors are applied prior to the analysis to give design values that are used in the calculation. The final result is an over-design factor, which must be greater than 1 to ensure the serviceability limit state requirement is satisfied.

Viewing Partial Factors

To view the partial factors that will be applied in the analysis, click the View button below the selected Design Standard.

Adding User-Defined Standards

To add a user-defined standard to the selection list:

1. Click Add
   
2. Select a standard from the drop-down to define initial values and click OK.
3. In the Partial Factors dialog, enter a user-defined value for any factor.
4. Enter a Name.
5. Click OK.

To import, export, or delete a user-defined standard, click the appropriate button and follow the on-screen instructions.
