摘要
本文针对当前国内外应用应力波反射法验桩中，常遇有较难解决的激振、突出桩底反射信号、不同缺陷性质反射波特征的识别和频谱分析资料的利用等几个技术性问题，提出了解决这些问题的办法和建议．
During using stress wave reflection method for testing piles, several difficult problems such as excitation, clear showing the reflection signal of pile bottom. characteristics of reflection wave for different defective properties and the usage the frequency analysis materials often appear, the paper gives the methods and suggestions for sloving these problems.
