DAMPING CONSTANTS FOR PILE DRIVEABILITY CALCULATIONS

A discussion of the form of damping law which should be used in the wave equation analysis is given. It is concluded from published data and the results of laboratory tests on small piles that damping depends on velocity in a highly non-linear manner. A power law is proposed to take account of this and a laboratory test facility for measuring the constants is described. Failure to take proper account of non-linearity in the damping law can give misleading results in the interpretation of field data by the wave equation. For clays side damping constants are found to be greater than point damping values.(a) (TRRL)
