1 Rock mass classification - Rocscience Inc.

Rock mass classification 5 's RQD was widely used, particularly in North America, after its introduction. Cording and (1972), Merritt (1972) and and (1988) attempted to relate RQD to Terzaghi's rock load factors and to rockbolt requirements in tunnels. In the context of this discussion, the most important use of RQD is as a component of the RMR and Q
