Scaling Wedges Overview

UnWedge always initially calculates the maximum sized wedges which can form around an excavation. Wedge scaling is important because the assumed wedge size can have a significant effect on support requirements (e.g., pattern spacing, positioning or orientation of bolts, and the thickness or strength of shotcrete).

There are several ways of scaling these wedges, to represent the actual size of wedges observed in the field:

• Tunnel Length
• Joint Structure Continuity
• Scale Wedges dialog
