桩检反射波记录的时域和频域分析

Time Domain and Frequency Domain Analysesof Reflected Wave Records for Pile Detection

该文简介了反射波测桩记录的时间域、频率域分析的基本原理和实质 ,并应用这一原理对几个工程的实测记录进行了时间域和频率域的分析 ,说明这两种分析是可以互相补充验证的 ,从而可以提高对桩检记录判释的可靠性。

The paper briefly introduces fundamental principle and essentials of time domain and frequency domain analyses of reflected wave records for pile detection. The theory has been applied in time domain and frequency domain analyses for measured records of several engineering projects, which indicates that both of the analyses may be supplemented and verified mutually, so as to enhance the reliability of interpretation of the records pile detection.
