摘　　要：试图应用积累的实测资料,阐明如何通过桩底反射波的幅值和形态推断桩身完整性。此外,还对无桩底反射波的现象进行了试验研究,并提出引发该现象的三种原因。This paper attempts to explain how the integrity of piles can be evaluated by the magnitude and figure of reflections from the pile toe,using the information accumulated from testing practice.Apart from this,the phenomenon that there is no reflection from the pile toe has been studied experimentally,and three reasons causing this phenomenon are presented in this paper.
