地质雷达在铁路隧道工程钢筋钢架检测中的应用

Application of the Ground Penetrating Radar on the Steel reinforcement and frame Detection of a Railway Tunnel Project

隧道工程质量影响着铁道运营,大量的铁道隧道病害表明,钢筋、钢架的缺失是导致隧道病害发生的重要原因。为了严格控制隧道工程的钢筋、钢架施工质量,运用高效率、高分辨率和图像直观的地质雷达无损检测成为了隧道质量检测的重要内容。在简述相关理论的基础之上,分析了地质雷达检测铁路隧道钢筋、钢架的几个典型案例。

Tunnel projects quality influences the operation of railways. A large number of railway tunnel diseases show that the lack of steel bars and frames is the important cause of occurs of the diseases. In order to strictly control the construction quality of steel bars and frames, the applications of ground penetrating radar, which has high efficiency, high resolution and intuitive images, are the important contents of tunnels testing. This paper analysizes some typical cases of application of ground penetrating radar to testing tunnel steel bars and frames , on the basis of the relevant theories.
