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.

Dynamic test signals of a pile with the wavelet method were analyzed. The traditional testing data of stress wave reflection were used. More information about propagating process of stress wave in the pile was obtained by getting ride of errors from the actual measured signals. The results of some examples demonstrated that the proposed meth-od has better accuracy and flexibility.
