中文摘要	An analysis of the behavior of spherical elastic wave radiation from an impulsively loaded cavity embedded in an infinite space has been carried out. It is confirmed that the propagating waveform is dominated by the natural vibration mode of the cavity and the magnitude of the dominant response depends only on the impulse of the time function of the load, and not the profile of the time function. This finding supports the fact that the dynamic signals recoded away from the blasting explosive contain mainly the characteristics of the natural vibrations of the geological structures near the cavity created by a blast. Based on this finding, two promising methods are proposed for the identification of geo-structures and parameters. (c) 2005 Elsevier Ltd. All rights reserved.
