Failed/Invalid Wedges

Show Failed Wedges

The Show Failed Wedges option in RocPlane highlights the distribution of failed wedges (i.e., wedges with a Factor of Safety of less than 1) on Histogram or Scatter plots. The option is available on the Chart menu and the right-click menu.

When Show Failed Wedges is toggled on:

• On a Histogram plot, the distribution of failed wedges will be superimposed over the total distribution, and coloured red.
• On a Scatter plot, each data point representing a failed wedge will be coloured red.

The Show Failed Wedges option is very useful because it allows you to see the relationship between wedge failure and any given input variable (e.g., Friction Angle) or output variable (e.g., Wedge Weight).

NOTE: On a Safety Factor Histogram, the failed wedges (safety factor less than 1) are ALWAYS highlighted in red. The Show Failed Wedges option is in effect by default, and is not available as a menu option for a Safety Factor Histogram.

Include Invalid Wedges

The Include Invalid Wedges option in RocPlane includes invalid wedges in Histogram, Cumulative, and Scatter plots. The option is available on the Chart menu and the right-click menu. When there are no invalid wedges in results, the option is grayed out.

Filter Out Safe Wedges

The Filter Out Safe Wedges option in RocPlane only plots wedges that have failed (i.e., F<FDesign) in Histogram and Cumulative plots. The option is available on the Chart menu and the right-click menu. When there are no failed wedges in results, the option is grayed out.
