| 摘 要： | 目前,我国在桩基质量无损检测中使用的仪器主要是时间域的,因此其成果的解释也以时间域分析方法为主。但是频率域的分析较为直观,有其独特之处。本文通过介绍桩基激振响应的波动方程在频率域中的解,对桩基质量在频率域中的分析方法作粗略的探讨。

| Abstract: | At present, the instruments used in non-destructive inspection of pilefoundations in China mainly belong to the time domain, so that the interpre-tation of its results mainly adopts the analytical method of time domain.Nevertheless, the analysis of frequency domain is characterized by directperception through the senses and therefore has its unique merits. Throughdescribing the solution of the wave equation for excitation response of pilefoundation in the frequency domain, this paper makes a rough discussion onthe analytical method for pile foundation quality in the frequency domain. |
