地质雷达在隧道衬砌厚度检测中的准确度分析

Analysis on Accuracy in Detection of Tunnel Lining Thickness by Geological Radar

从隧道衬砌检测为切入点,论述了地质雷达在隧道衬砌厚度检测中,由于忽略或不够重视介电常数的修正、里程标注、天线操控等环节,造成检测结果准确度不高;针对这些环节逐一地进行分析,证实其对检测准确度的影响很大;强调了在检测工作中应认真掌握这些环节的技术要点,提高检测工作的准确度。

Starting with tunnel lining detection, this paper discusses poor accuracy in the detection of lining thickness caused by negligence or disappreciation of dielectric constant correcting, mileage marking or antenna control, in respect of which analysis is carried out successively and their large effect on the accuracy of detection is proved. As a result, it is stressed that the keys in these links should be grasped carefully in practice, ensuring the accuracy in such detection.
