地质雷达在隧道塌方处理效果检测中的应用

The application of geologic radar detection in collapse treatment of tunnel

地质雷达探测利用无线电波对不可见目标体进行扫描，以确定其内部结构形态和位置，在检测隧道衬砌中，具有无损、快速和高分辨率等特点，介绍了地质雷达的原理及其探测方法，并结合实践，阐述了初期衬砌支护完成后塌方段处理效果检测的应用及其分析，分析结果表明了使用地质雷达技术的优越性。

Geologic radar utilize radio wave to scan invisible objectives to determine their positions and structural forms, which is superior in tunnel lining detection with non-destruction, high resolution and other advantages. This paper introduces the working principle of geologic radar as well as its detection method. Combined with practical work its application in treatment effect evaluation of collapse is elaborated, which shows the advantages of this technique.
