What is Rock Mass Classification in Engineering about?

This document discusses and compares the Rock Mass Rating (RMR) and Q-system rock mass classification systems. - RMR uses an additive rating system based on rock characteristics, while Q-system uses a multiplicative quotient system. - Both systems consider intact rock strength, degree of jointing, joint characteristics, and groundwater conditions. However, RMR also considers joint orientation, length, and separation while Q-system considers rock stress levels. - Q-system provides a more comprehensive e
