摘要
探讨了Kirchhoff成像技术在地质雷达路面无损检测的应用原理、方法及意义。以京珠高速公路潭耒段路面无损检测为例,分析总结了Kirchhoff成像技术在地质雷达路面无损检测中的应用效果,并与钻孔结果对比,表明Kirchhoff成像技术在地质雷达路面无损检测中能更准确的判断路面厚度、缺陷位置及大小形态,在一定程度上提高了地质雷达路面检测的探测精度。
Discusses the application principle,method and significance of Kirchhoff imaging tech- nology in geological radar pavement nondestructive testing. To the pavement nondestructive testing of bei- jing-zhuhai expressway pool Lei section for example. Analyses and summarizes the application effect of Kirchhoff imaging technology in geological radar pavement nondestructive testing, and by contrasting the drilling results , it indicates Kirchhoff imaging technology in geological radar pavement nondestructive tes- ting could be more accurate judgme-nt pavement thickness, defect location and size form. In a certain ex- tent, improves the detection precision of geolo-gical radar pavement nondestructive testing. To provide a reference for other engineering practice.
