摘要
探地雷达采用了先进的连续透视扫描无损探伤技术,能够快速而又非常简便地对隧道衬砌的实际情况进行检测。不同的衬砌缺陷对电磁波具有不同的反射特性,表现在探地雷达图像上具有不同的图像特征。本文简要介绍了探地雷达隧道衬砌质量检测技术,数据采集过程中的测线布置和参数设置,系统研究了衬砌不同缺陷类型的雷达图像特征,据此提高隧道衬砌质量检测中探地雷达图像的解释精度。
Ground - penetrating radar uses a continuous perspective advanced NDT scanning technology to quickly and very easy on the tunnel lining to detect the actual situation. The lining of different defects on the reflection of electro- magnetic waves with different reflected characteristics, have different image characteristics in the ground - penetrating radar images. This paper briefly describes the tunnel lining quality of ground - penetrating radar detection, the data col- lection process in the measuring line layout and parameter settings, systematic study of the lining of different defect types of radar image features, thus improving the quality of detection of tunnel lining in ground - penetrating radar images of interpretation accuracy.
