Technical Specifications

Analysis Options

  • Duncan Fama solution for ground reaction curve
  • Carranza-Torres solution
  • Vrakas and Anagnostou solution
  • Lee and Pietruszczak solution
  • Barbosa solution
  • Vrakas (2016) solution
  • Plot long-term ground reaction curve (specify strength reduction factor)
  • Deterministic (safety factor) or probabilistic (probability of failure) analysis

Probabilistic Analysis

  • Monte Carlo or Latin Hypercube simulation
  • Random or pseudo-random sampling
  • Random variables—all tunnel and rock parameters can be defined as random variables
  • Statistical distributions—normal, uniform, triangular, beta, exponential, lognormal, gamma
  • Histogram, cumulative, and scatter plots
  • User-defined plot variables
  • Best-fi t distribution and regression line
  • Highlight support failure on histogram and scatter plots
  • One-click export of charts to Excel

Rock Parameters

  • Elastic properties: Young’s Modulus, Poisson’s Ratio
  • Strength properties: Mohr-Coulomb or Generalized Hoek-Brown
  • Equivalent Mohr-Coulomb parameters can be calculated from Hoek-Brown parameters (GSI, mi, intact UCS, D)
  • Built-in charts and tables help estimate suitable values of GSI, mi, intact UCS, and D
  • Peak and residual strength parameters for Generalized Hoek-Brown criterion


  • Pre-defined support types for rock bolts, steel sets, and shotcrete
  • Combine multiple support types (e.g., rock bolts and shotcrete)
  • Simple parametric analysis —add, change, or remove support with a few mouse clicks
  • User-defined support
  • Support installation—specify distance from face or tunnel convergence
  • Interactive positioning of support
  • Longitudinal deformation profile —built-in or user-defined function
  • Custom support option for each of the three support types
  • Steel set reinforcement database

Tunnel Parameters

  • Tunnel radius
  • In-situ stress

Viewing Options

  • Ground reaction and support reaction views
  • Tunnel section and plastic zone radius views
  • Customize display options
