燃气管网是城市能源输送的基础和保障，准确的管道平面位置和埋深是燃气公司运营管理、建立GIS系统的重要信息。近年来，PE管由于防腐能力强等优点被广泛应用于中、低压城镇燃气输送中，由于PE管为惰性材料，非金属、不导电、不导磁，确定其在地下空间的位置一直是管道探测领域的难点。通过分析探地雷达的探测原理及其定位方法，研究了无示踪线敷设的PE管道在探地雷达中的成像特征及其与钢质管道、电缆等的区分方法，并分析了拐点、三通、带有套管的PE管道的确定方法，开挖验证了探测方法的可行性与精度，研究结果对提高PE管道的探测精度，建立燃气管网信息系统，确保管道安全运营等具有理论和现实意义。

Gas pipeline is the basis and guarantee of urban energy delivery, and hence accurate pipeline plane position and buried depth are important information for gas company operations management and the establishment of the GIS system. In recent years, due to the advantages of anticorrosion capability, PE pipeline has been widely used in medium and low pressure town gas transmission. As PE pipe is an inert material which is non?metallic, conductive, permeable, so it's difficult to determine its position in the underground space. In this paper, the authors analyzed the detecting principle and locating method of geological radar, studied imaging characteris?tics of PE pipeline in geological radar and the method for distinguishing steel pipe from cable, and investigated the inflection point, tee with casing, PE pipe. In addition, a method for determining the feasibility and accuracy of detection method was verified by the excava?tion. The research results have important significance in improving the detecting precision of PE pipeline as well as the gas pipe network information system.
