Abstract
According to their case study the authors recommend to use seismic velocities, especially shear wave velocity to characterize the rock mass instead of classical rock mass classification systems. Their experimental work includes a case study comparing the RQD, RMR and Q-value with seismic velocities in a tunnel excavated in granitic rock. The best correlation of shear-wave velocity with RQD was about 90%. Using seismic transmission the rock properties are predictable by non-destructive methods. Furthermore the hydrogeological parameters of rock masses are predictable by vp/vs as well.
