Abstract：

In this paper, the harmfulness of piling vibration, the stress wave of piling vibration, the law of energy transmission, various factor governing the harmfulness caused by piling vibration, and the mechanism of piling vibration harmfulness are analysed; the method for monitoring piling vibration, the standard for its rating, and the measures for reducing and isolating vibration are suggested. In addition, the measures for preventing and eliminating piling vibration are discussed in combination with surveyed data obtained in two construction sites.Keyword: Piling vibration harmfulness.
