以我国东部某管道沿途多处穿/跨越高压交/直流输电线路、城市地铁、高铁等城镇基础设施为背景，对管道沿线各种参数（如：通断电电位、交流干扰电压、电流密度等）进行现场监检测和理论分析。通过干扰源调研比对获得管道沿线各段受干扰类别和规律，并在此基础上总结了各类基础设施干扰的识别方法，为其他类似干扰的识别工程提供了参考。

Based on the fact that some urban infrastructures such as multiple high-voltage AC/DC transmission lines, urban subway and high-speed railway, often cioss/span over a pipeline in the east of China, various parameters along the pipeline (such as on-off potential, AC interference voltage, current density, etc.) were monitored on-site and analyzed by theory. Through the comparison of interference sources, the types and laws of the disturbed sections along the pipeline were obtained. Based on these, the methods to identify the interference of various types of infrastructure were summarized, which may provide reference for the identification of other similar disturbances.
