| Abstract: | The pile foundation tests are made in a building site of Zheng- zhou by the low-strain reflected wave method. Applying synthetic analysis methods of time-domain and frequency-domain, and the theory of wave velocity analysis, the integrity and quality of the pile foundations are systematically analyzed; moreover combining with the interval analysis of wave velocity, the intensity-wave velocity relation is expounded and proved; a quality appreciation for the pile foundations is made. The practice indicates that the integrity and flaw types of foundation piles can be exactly and effectively tested by this method. |
