When the defect of pile body is located at the range of one - dimensional blind areas, the wave form of the reflected wave distorts and shows the characteristics of strong amplitude and low frequency.
当桩身缺陷位于一维“盲区”范围时,反射波波形畸变,并呈强振幅,低频率之特征。

This paper reveals this law by engineering practice. Thence, it deepens the correlative understanding of the wave motion character of the reflectedwave with the structure of pile body.
