摘要
高频地质雷达检测具有操作方便、快速便捷、高效实用及无损等诸多优点,目前在公路隧道病害检测中发挥着非常重要的作用。本文从地质雷达基本组成、基本原理及数据处理流程出发,结合具体工程实际对公路隧道典型缺陷病害雷达特征信号和图像进行分析解译。最后,总结出几条针对公路隧道典型缺陷病害的特征信号分析方法,方法不仅能提高高频地质雷达检测数据的可读性、准确性及关联性,而且在地下管道探测、铁路、地下空洞及路基病害检测中也具有重要的参考价值。
High frequency geological radar detection has many advantages,such as convenient operation,rapid and convenient,efficient and practical and non-destructive,which plays a very important role in high-speed tunnel special detection today.Refer to the specific engineering practice,this paper analyses the typical defects interpretation highway tunnel disease characteristics of radar signal and image,which based on the basic composition,basic principle and data processing process of geological radar.Finally,Several characteristic signal analysis methods for typical defects of highway tunnels are summarized,which not only improves the readability,accuracy and relevance of high frequency geological radar detection data,but also has important reference value in underground pipeline detection,railway,underground cavity and subgrade disease detection.
