An Empirical Approach for Tunnel Support Design through <i>Q</i> and <i>RMi</i> Systems in Fractured Rock Mass

Empirical systems for the classification of rock mass are used primarily for preliminary support design in tunneling. When applying the existing acceptable international systems for tunnel preliminary supports in high-stress environments, the tunneling quality index (<i>Q</i>) and the ro...
