抄録（英）：
The Geotomography technique has been conveniently applied in various fields. There are two kinds of analyses : namely, velocity distribution and energy distribution mappings. Propagating wave velocity analysis shows neither detailed joint behavior nor change of apertures. Then the authors have been carrying out the laboratory tests to investigate the change of propagating wave amplitude through a specimen with a single artificial joint under tconstant contact pressure. It is considered that, knowing damping effect in a discontinuous body, the distribution of joints and the variation of respective joint apertures can be detected by propagating wave amplitudes and it provides more useful and reliable information on jointed rock masses than the conventional method based on propagation velocity.
