基于三维探地雷达技术的城市管线探测方法研究

Research on Urban Pipeline Detection Method Based on 3D Ground Penetrating Radar Technology

以某市地下管网探测工程为例,研究了三维探地雷达技术在管线探测中的实际应用。阐述了地下管网探测工程概况和探测现场布置,然后根据实际工程数据,对三维探地雷达探测结果进行了研究,研究表明,根据雷达双曲线特征能够准确判别出地下充水管线和充气管线,并且中心频率为500 MHz的雷达天线图像分辨率和清晰度更高。

This paper takes an underground pipe network detection project as an example to study the practical application of 3D ground penetrating radar technology in pipeline detection.This paper expounds the general situation of the detection engineering of underground pipe network and the layout of the detection site,and then studies the detection results of the three-dimensional ground penetrating radar according to the actual engineering data,according to the hyperbolic characteristic of the underground pipeline,the underground water-filled pipeline and gas-filled pipeline can be identified accurately.
