Overview

The Tunnel and Rock Parameters dialog allows you to define the tunnel and rock properties for your RocSupport model. To access this option, select Tunnel Parameters from the toolbar or the Analysis menu.

The following parameters are entered in the Tunnel and Rock Parameters dialog:

• Tunnel Radius and In-Situ Stress
• Elastic Properties
• Strength Properties

The appearance and required input data for the Tunnel and Rock Parameters dialog, will depend on the Solution Method and Analysis Type selected in Project Settings:

• The Strength Properties which are required will depend on the Solution Method you have selected in Project Settings (Duncan Fama, Carranza-Torres, Vrakas and Anagnostou, etc.).
• If you are carrying out a Probabilistic Analysis, then the Tunnel and Rock Parameters dialog will be presented in a grid format, which simplifies the input of statistical parameters for the variables.

When you are finished entering data click on the Apply button to accept changes and view results. Clicking on the Close button, without selecting Apply, will close the dialog without applying changes.

Minimizing / Maximizing the Dialog
