THEORETICAL AND EXPERIMENTAL STUDY OF THE DYNAMIC MODULUS OF ROCK MASSES

ETUDE THEORIQUE ET EXPERIMENTALE DU MODULE DYNAMIQUE DES MASSIFS ROCHEUX

Based on the use of seismic methods for rock mass evaluation, the article discusses the possibility of calculating the dynamic modulus of a rock mass. Laboratory and in-situ tests are described which evaluate the natural frequency of rock. Reasons for the differences between static and dynamic moduli are discussed. It is concluded that the visco-elastic theory studied makes it possible to relate the dynamic and static moduli to seismic quantities. The experimental and theoretical results make it possible to analyse the behaviour of rock masses. The seismic test described also makes it possible to obtain an exact order of magnitude of the static modulus of rock and of the order of magnitude that can be expected in sounding tests. The paper was originally published in Revue de l'Industrie Minerale 1968 Vol 80(8) p.373-600. (TRRL)
