Ground Reaction Curve
Easily estimate deformation of circular excavations in weak rock. Using tunnel radius, in-situ stress conditions, rock parameters, and support parameters, RocSupport calculates a ground reaction curve and a support reaction curve. The intersection of these curves determines the factor of safety for the support system.

Support Options
Install combinations of rockbolts, steelsets, shotcrete, or custom supports. You can select from a library of predefined supports using manufacturer specifications. Define support installation as the distance from the tunnel face, by percentage of tunnel convergence or by tunnel displacement.
Deterministic or Probabilistic Analysis
Compute a factor of safety with deterministic analysis or determine the probability of failure for probabilistic models using convergence-confinement analysis. Model variability in tunnel radius, in-situ stress, and rock material properties by assigning statistical distributions to variables. Generate histogram, cumulative, and scatter plots of statistical data.
