【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。更多还原

【Abstract】 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.更多还原
