摘　　要：城镇地下燃气管道的运行状况直接关乎城镇的安全。管道电流测绘技术可以在非开挖条件下对埋地管道的阴极保护有效性做出评价,有效地检测出埋地钢质管道外防腐层缺陷。在工程应用中,采用这种新颖的检测技术可以快速检测和定位某处地下燃气管道的外防腐层缺陷。The running state of theurban underground gas pipeline is crucial to the city safety. The pipeline current mapping technology is able to evaluate the effectiveness of the cathodic protection of the underground pipeline without excavation and effectively detect the defects of the anti-corrosion coating of the underground steel pipeline. In engineering application, the defects of the anti-corrosion coating of the underground gas pipeline can be detected and located rapidly by using this new detection technology.
