Abstract
The measurement of elastic wave velocity is effective as the technique which grasps elastic characteristics of rock, and recently the evaluation by S wave is mainly carried out. In this paper, it is tried to develop the simultaneously measured system for P, S wave velocities and electric resistivity of a rock sample and to manufacture the laboratory equipment. In this system, P and S wave are analytically found out from the recorded waves. And on the same time, the electric resistivity of this rock specimen is measured by geo science method. Furthermore, P, S wave velocities and electric resistivity obtained from this system are compared with these quantities given by the usual measurement methods. As the results, it is confirmed that this measurement system is useful for the various rock specimens.
