摘要
本文通过对基桩桩身浅部缺陷与低应变动测应力波首波振幅特征关系进行分析 ,就目前检测系统中使用的自动增益控制 (Agc)和浮点放大技术导致的缺陷漏判问题提出了改进意见。
This paper is deals with the relationship between shellow defect of pile and its first peak amplitude of low strain dynamic test signal, and some ideas has been given for the improvement of defect induced by using automatic gain control and floating point amplifier techniques.
