Selection and Application of Vibratory Piling Hammers

Vibrating force and amplitude of vibration to drive piles to the required depth are the key parameters for selection of vibratory piling hammers.However,there have been no similar design and construction criteria in China and the bases for design theories are not complete,hence,it is very difficult to calculate the vibrating force and amplitude of vibration of a vibrating piling hammer when selection is made.Some foreign and domestic empirical equations for these calculations were collected and re-arranged during the piling operations for building foundations in some large engineering projects to verify the procedures for selection of vibratory piling hammers and the relevant calculating methods.The results proved that the piling hammers have been successfully selected.
