<p>PURPOSE:To obtain the accurate orienting method for a slope rupture position by AE measurement using a waveguide having AE sensors at both ends. CONSTITUTION:A waveguide 1, to both ends of which AE sensors 2 and 3 are attached, is arranged in a natural ground K, and the AE waves generated in the ground are measured. The data, which have reached the AE sensor 2 and 3 and can orient the position, are selected. The individual AE-wave characteristic, with which the position is oriented, is investigated. The position of the slope rupture is oriented based on only the result of the orientation of the position that is judged as the AE wave from the same generating source as the evaluating data.</p> |
