Rock Mass Rating (RMR) is a rating system proposed by Bieniawski (1989) to classify rock based on five classification parameters.
This Python module is developed based on [1], [2].
Parameters:
-----------
r1 : strength rating
r2 : Rock Quality Designation (RQD) rating
r3 : space of discontinuity rating
discontinuity_class : condition of discontinuity rating
r5 : ground water rating
Return(s):
----------
RMR89 / rock mass rating value which consists of:
- Rating value
- Class number (I, II, III, IV, V)
- Description (Very good rock, Good rock, Fair rock, Poor rock, Very poor rock)
