Create Stereonet

A stereonet plots slope and slope direction (dip and strike) of the poles of discontinuities onto a two-dimensional graph. This helps to identify discontinuity sets and analyse the stability of rock slopes.

Creating a stereonet

Follow this procedure to create a stereonet from discontinuity data:

1. On the Geotechnical tab, in the Stereonet group, click Create Stereonet.

2. Add discontinuities to the Stereonet data field.

   

3. Choose any of Poles, Planes, and Intersections as the preferred representations of discontinuities on the stereonet. You can select these globally or individually to suit requirements.

4. If you selected Intersections in step 3, select the preferred Intersection method from the following:

   • All vs All: The stereonet tool will generate intersections between all discontinuities.
     

   • Set vs Set: The stereonet tool will generate intersections between discontinuities from different sets, but not between discontinuities in the same set.
     

5. Click OK or Apply to create a new stereonet in the geotechnical container.

Stereonet view options

Open the stereonet in a new view window, which will display the stereonet view toolbar.

Configure the stereonet with the available functions. See View Window Toolbars > Stereonet toolbar for details.

Note:  You can also add contours to the stereonet data to help identify data of interest. See Stereonet Contours.
