摘　　要：针对变电站改造和新建过程中由于勘测不足和资料缺失而导致地下隐蔽管线被挖断的问题,提出将探地雷达技术应用于变电站的地层隐蔽管线定位与识别中。首先,通过正演实验分析了常见不同地层介质的灰度图特征;然后,根据单道波形图对典型金属、非金属介质以及电缆的探测波形特征及形成原因进行了系统性分析与总结;最后,通过在宜昌市某110kV变电站中进行的反演实验对探地雷达技术在变电站地层隐蔽管线探测中的应用进行了验证。实验结果表明:使用探地雷达技术能够很好地对地层隐蔽管线进行定位和识别,该技术在变电站改造和新建过程中具有良好的应用优势与应用前景。Aiming at the problem that the underground concealed pipeline is cut off due to insufficient survey and lack of informa-tion during the reconstruction and new construction of the substation,the ground penetrating radar technology is applied to the loca-tion and identification of the concealed pipeline in the substation.Firstly,the gray-scale features of common formation media are analyzed by forward modeling.Then,according to the single-channel waveform diagram,the characteristics and formation causes of typical metal,non-metal media and cable are systematically analyzed and summarized.Finally,the application of ground penetrat-ing radar technology in the detection of concealed pipelines in the formation of the substation is verified through the inversion exper-iment carried out in a 110 kV substation in Yichang.The experimental results show that ground penetrating radar technology can precisely locate and identify concealed pipelines.This technology has good application advantages and prospects in the new con-struction and reconstruction of substations.
