Abstract

The invention provides a tunnel lining gridding fine detection method and system based on a three-dimensional geological radar, and the method comprises the steps: enabling a three-dimensional geological radar device and a gridding fine detection trolley to be combined to serve as a fine detection scanning mechanism; based on an array antenna technology, a tunnel lining is scanned in a full-coverage mode according to a scanning mode considering the longitudinal direction of a ring to collect lining internal data, the detected data are uploaded to a detection host and a far-end server system in real time, and then three-dimensional reconstruction is carried out on the detected lining internal data of each grid unit based on the spatial position of a grid. After optimization processing, three-dimensional expression of detection data is realized through a synthetic aperture focusing imaging three-dimensional data processing method, high-quality radar detection data is formed, and lining internal defects are identified. By the adoption of the scheme, full-coverage non-contact detection of the tunnel lining structure can be achieved, the problems that an existing lining detection technology is insufficient in comprehensiveness and low in operation efficiency are solved, the detection precision is high, consumed time is short, and practicability is high.

本发明提供了一种基于三维地质雷达的隧道衬砌网格化精检方法及系统，该方法将三维地质雷达装置与网格化精检台车组合设置作为精检扫描机构，基于阵列天线技术按照兼顾环纵向的扫描方式全覆盖扫描隧道衬砌采集衬砌内部数据，将检测得到的数据实时上传到检测主机和远端服务器系统，进而基于网格的空间位置对检测得的各网格单元衬砌内部数据进行三维重构，经优化处理后通过合成孔径聚焦成像三维数据处理方法实现检测数据的三维表达，形成高质量的雷达检测数据并识别衬砌内部缺陷。采用该方案能够实现隧道衬砌结构的全覆盖无接触检测，克服了现有衬砌检测技术全面性不足、作业效率低的问题，检测精度高，耗时少且实用性强。
