combining RMR, Q and RMi
The RMR, Q, and RMi combined classification system
The main rockmass classification systems make use of similar rockmass parameters. It is therefore possible to combine the input parameters to three of the systems into a set of common parameter tables. This enables the ground quality to be found directly in these systems from only one set of input parameters. Thus, the estimated rock support found in one system can be easily be compared and checked in the other systems.
