General

Units

The first drop-down menu of the General tab allows the user to select the units of the project.

Analysis Type

In the Project Settings dialog, you may choose either Deterministic or Probabilistic for the Analysis Type. See the Analysis Type topic for more information.

Solution Method

You can choose from five solution methods in RocSupport. See the Solution Method topic for more information.

Modulus Estimation Method for Generalized Hoek-Brown Materials

You can choose from three methods in RocSupport. See the Modulus Estimation Method topic for more information.

Plot Long-Term Curve

The RocSupport Solution Method computes the Ground Reaction Curve based on initial assumed material properties and loading conditions. To account for long term tunnel behaviour (e.g. rock mass property deterioration, re-establishment of groundwater regimes, creep, etc.), a strength reduction factor can be applied to obtain a long term Ground Reaction Curve (Hoek, 2003). See the Long Term Ground Reaction topic for more information.
