Joint Frequency

The Joint Frequency option allows you to plot the Joint Frequency calculated from distance measurements recorded along a Linear or Borehole Traverse. This is a simple 1D frequency measured as joints per meter (metric) or joints per foot (imperial) along each interval.

In order to use the Joint Frequency option:

1. You must have at least one (or more) Linear or Borehole Traverses defined (e.g., Linear, Linear BH Oriented Core, Linear BH Televiewer, Curved BH Oriented Core, Curved BH Televiewer).
2. The Distance Column must be enabled (checkbox in Project Settings) and Distance values entered in Grid Data view.

If the above 2 criteria are met:

1. Select Joint Frequency from the Analysis menu.
2. In the Joint Frequency dialog:
   1. Select all or any combination of individual Traverse(s). You can quickly select all or no Traverses using the Select All / Deselect All options.
   At least one Traverse must be selected.
   2. Select the Interval as either Discrete or Moving.
   3. Enter an Interval Value.
   4. Enter a Move Increment (if Interval = Moving).
   5. Apply Terzaghi Weighting to the joint count by selecting the Weighted checkbox.
3. Select OK and a graph of Joint Frequency along the length of the selected Traverse(s) will be plotted.
