  • Patent number: 3946598
    Abstract: The dynamic parameters of soil in situ are determined by: impacting freely suspended piles and measuring the force applied to and the acceleration of the piles; analyzing the measured information to determine the transfer function (impedance) of the piles; driving the piles into the soil whose dynamic parameters are to be determined; impacting one of the piles driven into the soil; measuring the force applied to and the acceleration of the driven pile; measuring the acceleration produced by the driven pile at at least one remote pile; analyzing the measured information obtained with the piles located in the soil to determine the transfer functions of the soil plus the piles; and, subtracting the transfer functions of the piles from the transfer functions of the piles plus the soil to determine the transfer function of the soil. The transfer function when plotted depicts the dynamic parameters of the soil.
