摘要
为提高缺陷识别的精度,提出一种基于声波透射法的市政桥梁桩基工程检测新技术.该方法融合了多通道声波数据同步采集技术、波形声波透射分析技术及三维声波成像重建技术,能够检测桩基内部的缺陷.其中,多通道声波数据同步采集技术用于采集声波信号,波形声波透射分析技术用于分析声波信号,三维声波成像重建技术用于构建桩身内部缺陷的三维分布图.实验结果表明,与传统的低应变法和钻芯法相比,所提方法在缺陷识别精度、检测效率、结果可靠性等方面具有突出优势,可为市政桥梁桩基质量检测提供有力支撑.
Abstract
To improve the accuracy of defect identification,a new technology for detecting municipal bridge pile foundation engineering based on acoustic transmission method is proposed.This method combines multi-channel acoustic data synchronization acquisition technology,waveform acoustic transmission analysis technology,and three-dimensional acoustic imaging reconstruction technology,which can detect defects inside pile foundations.Among them,multi-channel acoustic data synchronization acquisition technology is used to collect acoustic signals,waveform acoustic transmission analysis technology is used to analyze acoustic signals,and three-dimensional acoustic imaging reconstruction technology is used to construct a three-dimensional distribution map of internal defects in the pile body.The experimental results show that compared with traditional low strain method and core drilling method,the proposed method has outstanding advantages in defect recognition accuracy,detection efficiency,and result reliability,which can provide strong support for the quality inspection of municipal bridge pile foundation.
