000011298 520__ $$2eng$$aIn an extended effort to improve the borehole seismic methods, an in-hole seismic source has been developed and utilized in cross-hole and in-hole seismic measurements. The source has been developed to be fit in three-inch (76 cm) boreholes with key functions including a spring-loaded impact pestle, a servomotor triggering device and a mechanical coupler driven with two servomotors. The spring-servomotor mechanism of the source makes it possible to be used in uncased boreholes as well as cased ones. The source enables to reduce testing cost and to improve the accessibility of borehole seismic methods to practice engineers. Also the source can be incorporated to an in-hole probe for in-hole seismic method, which is performed in a single borehole so that the testing cost could be cut down further. The performance of the source has been evaluated with cross-hole and in-hole measurements at various sites.
