| Research Abstract |
The use of seismic tomography techniques, it can be evaluated comprehensively cross-sectional image as X-ray CT health infrastructure structure inside can not grasp the hammering test and visually. Which can be evaluated by surface projection image the soundness of the internal structure from one side, research leader we have established a method of one side arrangement type in addition. In this study, to obtain a form that can be used without having to implement hit the point of origin waveform estimation technique, a striking point of origin position location technique new to this technique, installing the sensor one by one blow outgoing lot of information and any. This hammering test response tomography technique, while performing hammering test simple, soundness of internal also allows a detailed evaluation by the projection image.
