针对老旧机场修建资料缺失的情况，采用地质雷达无损检测技术对道面结构进行了检测，通过研究地质雷达波在机场道面结构中的传播反射特征，分析了道面基层缺陷情况的雷达响应图像，采用了以反射波幅及道面钻芯取样厚度递推反算的方法，对机场道面结构层材料介电特性及其整体厚度进行了反算分析，现场检测结果表明，利用地质雷达分析道面的结构组成及缺陷情况具有良好的效果。

In view of the old airport lacking of building information,ground penetrating radar nondestructive testing technology was used to test the structure of airport pavement for the first time. By research the reflection characteristics of radar wave in pavement structure,analyzed the radar response image of the pavement-based defects,used the method of recursive inversion by the data of reflection amplitude and pavement core sampling thickness,to analysis the dielectric characteristic of pavement structure materials and the overall thickness of pavement,field application indicated that using ground penetrating radar to analysis the pavement structure and defects was satisfactory.
