How can I determine the volume or weight of material that may slip, based on the failure surface?

In the InfoViewer, the area of the critical surface can be found where the resisting and driving forces are presented. The surface horizontal width and average height are also displayed.

You can also add up the weight of the slices:

  1. In Slide Interpret, right-click on the surface of interest and select Add Query and Graph.
  2. The Graph Slice Data dialog will open. Select Export All Data.
  3. The Export Query Data dialog will open. Keep the Interslice Data option selected as the Data to Export. Click on Excel.
  4. Excel will open and you can add up the individual slice weights.
