| 摘 要： | 通过对基桩存在浅部缺陷时桩顶响应信号的小波分析，提取信号中所包含的对应于缺陷部位的应力波反射特征信息，可以实现对基桩浅部缺陷的准确定位。数值模拟试验显示了该方法的合理性；在此基础上，进行了工程桩的现场试验研究，结果表明该方法对基桩浅部缺陷的检测是可靠的。

| Abstract: | By analyzing the response signal of pile when it has shallow defects with wavelet transformation, the reflecting characteristics of the stress wave hiding in the original signal is obtained. This method can locate the shallow defects of pile accurately and be verified by numerical simulation experiment. The result of in-situ test is in good agreement with numerical simulation and it shows that this is an effective method and can be used in shallow defects testing of piles. |
