Abstract: The vibration caused by the pile’s dynamic driving may result in damage to the structure near the site. A vibration monitoring has been completed in a power plant project where prefabricated piles are driven dynamically. Based on the monitoring data, the relationship between the depth of the pile’s tip in the soil and the peak velocity of vibration on the ground has been established; and the property of the soil at the pile’s tip is thought to be the main factor for the vibration. In addition, the vibration on the ground is related to the character of elastic waves, thus the decay laws are different at vicinity and there far from the pile. Moreover, the damping ditch near the object to be protected is more effective to reduce the magnitude of vibration on account of the epicentre being in the deep soil.

Key words: prefabricated pile, dynamic driving, vibration, decay law, damping
