反射波数字处理技术在基桩无损检测中的应用

The data processing technique of acoustic reflection in piles inspection

本文通过对基桩无损检测的反射波时域波形分析,应用频谱分析、数字滤波、相关分析、三瞬计算等数字处理方法,配合进行基桩质量检测,结果发现反射波数字处理技术是提高解释精度的有效方法,对工程验桩有指导意义.

Through the analysis on the time-domain waves of acoustic reflection in piles inspection with the digital handling methods such as applied analysis of frequency spectrum, digital filtering, correlation analysis,tri-instant processing and so on,the author finds that these methods are accurate and efficient in piles inspection.
