对小波分析在基桩检测中的应用进行了研究，该方法利用传统的应力波反射法的测试数据，得到反映桩身中应力波传播的更多有用信息，消除了由实测信号直接读取反射波特性所存在的误差，具有较好的准确性和灵活性。

The present paper puts forward the object of studies on signals of dynamic test about piles with wavelet analysis. The traditional testing data of stress wave reflection is exploited. More available information, which expresses the propagating process of stress wave in piles, is obtained by getting ride of errors from actual measured signals. The conduction results, with some examples shown, demonstrate that this method can get more accuracy and flexibility.
