Abstract
Apparatus for supporting a vibrational shear wave transducer and coupling shear-wave energy into the earth's surface. The apparatus includes separate lateral base plate assemblies having the vibrator assembly operatively disposed therebetween, and the vibrator frame structure includes necessary hydraulic porting structure and supports manifold and servo valve control structure to provide a unitary, improved form of transducer apparatus. Each of the lateral base plate assemblies further includes a removable earth-coupling structure in the form of inverted pyramid or cleat structure having characteristic apex angles in both the lateral and longitudinal dimension so that earth coupling of energy is optimally effected.
