Abstract
In this article the use of the seismic properties of a rock mass to assess the geomechanical behaviour of the rock mass is examined and illustrated. The correlation between the values of seismic velocity and some basic parameters of rock mechanics, such as RQD and fracture frequency, have been established. Moreover, the relationships between the engineering rock-mass classification systems and seismic quality index (QI) have also been derived. The relationships have been derived from an investigation for a proposed dam in Wadi Mujib, Jordan. The ground conditions comprise colluvial and fluvial superficial deposits overlying limestones, mudstones, marls and shales. It is suggested that the relationships obtained in this study could be applied in areas that have similar lithological and structural characteristics.
