摘　　要：随着桥梁工程复杂性的增加,确保施工质量和结构安全性成为重要课题。目前,常用的非破坏性检测技术如声学扫描和探地雷达(GPR)在桥梁检测中显示出不同的优势和局限。文章通过对比声学扫描和GPR在桥梁工程施工质量控制中的应用,旨在评估两种技术在检测潜在缺陷和劣化方面的有效性。研究发现,声学扫描在检测表层缺陷时劣化面积检测率为0.82%,而GPR能更深入地探测到结构内部,其劣化检测率达到12.1%。研究结果表明,结合使用这两种技术可以更全面地评估桥梁的健康状况,为桥梁维护和修复提供科学依据,从而保证公路水运安全。As bridge engineering becomes more complex,ensuring construction quality and structural safety is crucial.Currently,common non-destructive testing techniques like acoustic scanning and Ground Penetrating Radar(GPR)have their own pros and cons in bridge detection.This paper compares the application of acoustic scanning and GPR in bridge construction quality control to evaluate their effectiveness in detecting potential defects.The study shows that the degradation area detection rate of acoustic scanning for surface defects is 0.82%,while GPR can detect deeper with a rate of 12.1%.The results indicate that using both technologies together can assess bridge health more comprehensively,offer a scientific basis for maintenance,and ensure transportation safety.
