Support Estimation Using Ground Reaction Curves
version 3.0
RocSupport is an easy to use software tool for estimating deformation in circular or near circular excavations in weak rock and visualization of the tunnel interaction with various support systems. Given the tunnel radius, in-situ stress conditions, rock parameters and support parameters, a ground reaction curve and a support reaction curve are calculated. The intersection of these curves determines a factor of safety for the support system.

| RocSupport is a fast and easy to use program for estimating the deformation of circular tunnels in weak rock and visualizing the tunnel interaction with various support systems. | Ground reaction curves (short term and long term) and support reaction. The intersection of these curves determines the safety factor of the support. |

| Safety factor histogram (probability of failure = 20%). | Scatter plot of Young's mudulus (rock mass) versus Safety Factor. |

| The appearance of the Tunnel section View can be customized with the Display Options dialog. | Display of probabilistic analysis results - histogram, cumulative and scatter plots. Tunnel section view is also shown. |

| Tunnel support in very weak rock, requiring heavy steel set and shotcrete support. |
RocSupport can be used as a tool for the preliminary design of tunnels and support systems. It can provide valuable information about various tunnel support options, before detailed analysis is carried out with a finite element program such as Phase2.
The program is applicable to tunnels excavated in weak rock under squeezing ground conditions. It is not applicable for excavations in hard rock, where failure is controlled by structural discontinuities or brittle failure.
