抄録

The shallow seismic reflection method has been used increasingly since 1980 in applications shallower than a few hundred meters for geotechnical and active fault surveys. The free-fall and accelerated types of weight drop have been used generally as a seismic source, however, it is difficult to operate such sources in urban areas because of damaging to paved roads.<BR>The sweep type source by using a electro-magnetic vibrator has been developed by one of the authors, which is based on the principle of the Vibroseis^® system. This type of seismic source, in which received signal is compressed into a wavelet by cross-correlation with transmitted signal, is characterized by higher S/N ratio, adjustable frequency range and possible operation in urban areas.<BR>The shallow seismic reflection method by using the sweep type source was applied to geotechnical surveys and some faults are detected in urban areas in Kinki district.
