UnWedge
Underground Wedge Stability Analysis
- Excavation
- Mining
- Tunnels
UnWedge assess possible perimeter and end wedges formed by three intersecting joints along an excavation. If more than 3 possible joint sets exist, UnWedge is also capable of evaluating all joint combintions.
Article: Multiple End-Wedge Support Patterns
Assess the stability of underground rock mines subject to in-situ water and field stress conditions.

Optimize tunnel axis orientation with the tunnel axis plot, and tunnel orientation analyzer. Assess the critical factors of safety and required support pressures of the tunnel over a range of tunnel axis trends and plunges.


Import joint orientation data from Dips into UnWedge including mean set plane orientations and set statistics, as well as user plane and grid data plane orientations.

-
Tunnel Orientation
Analyze a range of tunnel axis trends and plunges, as well as consider all joint combinations. Determine critical minimum or maximum values (i.e., Required Support Pressure, Factor of Safety, Wedge Weight, etc.) and the tunnel trends, plunges, and joint combinations which produce these critical conditions.
-
Multiple Bolt Patterns
Get more flexibility with the option to add multiple bolt patterns to end wedges or add bolt patterns to both ends of the tunnel independently.
-
Batch Compute
Save time with the Batch Compute feature which enables you to compute several deterministic and/or probabilistic UnWedge model files (.weg, .weg5) at once and quickly generate results to text or Excel format.
