摘要
Based on the applied results of detecting the pile foundation of the Ninde International Convention Center by the low strain method,it is considered that the reflected waves of phase opposition with incident waves are not always at the bottom of the reactivity by soil layers, the broken piles can also result in obvious reflected waves of the reversed phase in the low strain waveshape, for which it can carry out overall analysis and evaluation of the quality of the pile foundation and form a judgement of detecting results of the pile foundation.
