摘要
目前,国内桩基动测正由模拟记录方式向数字记录方式过渡,本文针对这一时期出现的一些技术问题,从推广应用数字处理技术的角度,系统地阐述了诸如数字滤波、非线性放大,倒频谱、频率细化等技术的应用方法,并以实例说明其效果,最后概要地介绍了笔者编写的实现上述技术的实用软件。
The pile testing in China is in process of transition from analogue method to digital approach. In view of some problems due to this development, the techniques of time-dependent amplification; digital filter; cepstrum and frepuence zooming as well as their application are elaborated systematiclly. At the end of this paper, a brief note on the speciai software-KFFT, which is designed to implement those ideas is presented with examples.
