摘　　要：采用抗混滤波器的检测仪与普通滤波器检测仪进行桩基低应变检测时 ,得到的波形不尽相同 .文中对这两种类型仪器的检测波形特征进行了分析研究 ,并根据反射波法原理得到了判断缺陷桩的类型、部位及程度的方法 ,从而达到更严格控制成桩质量的目的 .Different wave shapes can be acquired in pile foundation with small strain by means of different types of instruments for detecting. This paper researches their characters of wave shapes using two kinds of instruments, one of which has common filter and the other can resist mix. The types ,position and degree of pile defection can be well estimated according to the reflecting wave principle, so the quality of the pile foundation will be strictly controlled.
