地质雷达在运营隧道无损检测中的应用研究

Application of Geological Radar in Nondestructive Testing of Operating Tunnel

针对某运营期隧道,利用地质雷达高效率、高分辨率以及无损检测的优势,通过合理人员配置和规划,编制出合理的地质雷达无损检测方案,快速高效完成现场检测作业。经数据处理和合理分析后,准确检测出该运营隧道衬砌背后存在的厚度不足、背后脱空和不密实等典型衬砌缺陷,为后续运营隧道治理提供技术依据,保障铁路运营安全。

For a tunnel in an operation period,using the advantages of high efficiency,high resolution and nondestructive testing of geological radar,a reasonable geological radar nondestructive testing scheme is prepared through reasonable staffing and planning,so as to complete the on-site testing operation quickly and efficiently.After data processing and reasonable analysis,typical lining defects such as insufficient thickness,back void and non compactness behind the lining of the operating tunnel are accurately detected,so as to provide technical basis for subsequent tunnel treatment and ensure the safety of railway operation.
