Process and apparatus for analyzing and controlling energy transfer to the ground

摘要

A method and apparatus for determining the occurrence and behavior of energy transference processes to the ground includes a vibrator which transfer seismic energy to the ground. Force and velocity signals are derived from acceleration signals measured at the baseplate and a reaction mass. The signals are filtered and multiplied together. The output components are separated and used for regulating the vibrator or for determining transference losses in the soil.
