Movable device for generating acoustic shear waves in the earth |
摘要 |
A device for generating shear waves in the earth for seismic prospectives, comprising a target member coupled with the earth, a vehicle carrying a mass and means for driving and guiding the mass along a direction perpendicular to the striking surface of the target member and parallel to the earth surface, said means comprising a toothed wheel in mesh with a driving chain and a counterweight for balancing the mass.
