Analysis and application of tunnel typical defect characteristic signal of based on high frequency geological radar method
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 in-terpretation 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 meth-ods 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.
