地质雷达在隧道衬砌质量检测中的应用

Application of GPR Technique in Quality Detection of Tunnel Lining

地质雷达作为一种新型无损检测设备,因其快速、高效、分辨率高等优点迅速在各个工程行业得到推广。文章在阐述地质雷达工作原理的基础上,介绍了地质雷达检测工作方法、参数设置,并结合工程实践对隧道衬砌检测中遇到的衬砌界面、拱架与钢筋网、空洞、不密实体、地下水等波形的特征加以分析总结。

The Ground Penetrating Radar is a new testing device characteristic of high speed, efficiency, and discrimination, which is rapidly popularized in many engineering trades. Based on the principle of GPR, this paper introduces the methods of GPR and the parameter installation of the geology radar examina- tion method, as well as analyzing and expounding the different wave-shapes, such as lining interface, gantry and the reinforcement net, empty and non-secret entity, groundwater, which occurred in application of the examination of railway tunnel lining. Thus, a practical reference is provided for the similar engineering.
