弹性波检测孔道灌浆密实度的技术与方法研究OA

In response to the limitations of traditional detection methods,the research systematically investigates the applica-tion of elastic wave detection technology in evaluating the grouting density in ducts.The composition and detection procedure of the elastic wave detection system are introduced,the performance differences between this technology and traditional detec-tion methods are analyzed,and the effectiveness of the approach is validated through engineering case studies.The re-search demonstrates that a multi-parameter evaluation approach based on elastic wave velocity,amplitude attenuation and fre-quency components can enable precise detection of internal voids and looseness in ducts.The research findings provide a non-destructive testing solution for quality control in prestressed engineering.
