Underground Wedge Stability Analysis

Analyze underground tunnel excavations with intersecting discontinuities and visualize the model in 3D. Determine the stability of tetrahedral wedges formed along the tunnel perimeter and ends and calculate their respective support requirements to achieve the design factor of safety. Quickly create wedge models, factoring in the effects of shear strength, water, field stress, and supports.

Probabilistic Analysis

Obtain probability of failure for probabilistic models using limit equilibrium analysis. Model variability in joint orientation and strength, water pressure, field stress, and supports, by assigning statistical distributions to variables. Obtain wedge location-specific probabilistic plots (histogram, cumulative, and scatter) around the tunnel perimeter.

Support Designer

Achieve the design factor of safety by adding supports like pattern or spot bolts, layers of shotcrete, or uniform pressure to the boundary. The support designer provides specialized views for adding, editing, and visualizing perimeter and end supports. Evaluate the effectiveness of different support strategies and optimize designs to enhance stability and safety, all within an intuitive interface.

UnWedge Across Applications

  • Excavation
  • Mining
  • Tunnels

Excavation

Assess possible perimeter and end wedges formed by three intersecting joints along an excavation. Evaluate all joint combinations if more than 3 possible joint sets exist.

Placeholder

Mining

Assess the stability of underground rock mines subject to in-situ water and field stress conditions.

Placeholder

Tunnels

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

  • Tunnel Orientation

    Analyze a range of tunnel axis trends and plunges, considering all joint combinations. Determine critical minimum or maximum values (such as required support pressure, factor of safety, wedge weight) and identify the tunnel trends, plunges, and joint combinations that produce these critical conditions.

  • Multiple Bolt Patterns

    Enhance flexibility by adding multiple bolt patterns to end wedges or independently adding bolt patterns to both ends of the tunnel.

  • Vertical Shaft

    Design vertical shafts and analyze their stability by accounting for the effects of depth on the factor of safety and the support pressure required to achieve the design factor of safety.
