The RSR value of any tunnel section is obtained by summing the weighted numerical values determined for each parameter. The RSR concept is a very useful method for selecting steel rib support for rock tunnels. As with any empirical approach one should not apply the concept beyond the range of the

The RSR concept introduced a rating system for rock masses. It was the sum of weighted values in this classification system. There are considered two general categories:
