Abstract
In a bore holes, a plurality of resilient members and plates are piled up alternately to form a laminate, and a deadweight is dropped onto the laminate. The resilient members are deformed due to the impact force of the dropped deadweight to cause bore hole water among the plates to be forced out in the outward direction, and elastic waves to occur in the bore hole wall.
