隧道仰拱GPR无损检测实例分析
|
摘要
这里基于某铁路隧道仰拱400MHz天线探地雷达的实际采集数据,采用Radan7软件处理方法所检测的缺陷结果,与施工单位及相关质量控制单位所组织的破检验证完全相符。通过对检测缺陷展开全面分析与解释,为隧道缺陷检测提供了依据和方法,将其应用于该工区后续隧道施工和隧道缺陷的检测处理与解释,具有重要的现实指导意义。
Ground penetrating radar(GPR) method has become one of the most important and most effective means in quality inspection of tunnel lining since GPR has many characteristics such as economic,non-destructive,fast,intuitive,strong anti-interference,high resolution,easy to operate,enabling continuous measurement and so on.This paper combine with using of the Radan7 processing method based on the actual data of a railway tunnel invert collecting by a 400MHz antenna ground penetrating radar to test defects of tunnel invert,which are entirely consistent with the breaking certificate that is organized by construction units and the relevant quality control units.Then we carry out comprehensive analysis and interpretation of the detection defects.It provides the basis and methods for the tunnel defect detection.It has important practical significance for applying it to the detection processing and interpretation of tunnel construction and tunnel defects in the work area.
