摘要
By means of comparing the reflected curve and the dynamic stiffness with those of perfect piles under the same conditions, abnormalities of the reflected wave curve or of obvious low dynamic stiffness would be found from the concrete defect in the lower pile,from the bottom sediment thickness or the characters of pile bearing stratum. Through investigating the changes of the reflected curve and the dynamic stiffness before and after reinforcement and comparing the reflected curve and the dynamic stiffness after reinforcement with those of perfect piles under the same conditions, the reinforcement effect can be inspected.
