京沪高铁对埋地管道的交流干扰规律及缓解措施
AC Interference Law of Beijing-Shanghai High-Speed Railway on Buried Pipelines and Mitigation Measures
摘 要
京沪高铁山东段与某输油管道长距离并行交叉，导致输油管道遭受严重的交流干扰。通过现场检测和数值模拟评价，明确了高铁对埋地管道的干扰特性、干扰强度及分布规律、缓解方案等。经过排流施工和后评价，管道交流干扰问题消除。基于该工程案例，高速铁路与交流输电线路对管道交流干扰强度评价方法显著不同，数值模拟计算对合理设计动态交流干扰排流地床数量和接地电阻具有重要辅助作用。

Abstract
The long-distance parallel and crossing between of Beijing-Shanghai high-speed railway and an oil pipeline in Shandong province leads to serious AC interference to the oil pipeline. In this paper, the interference characteristics, interference intensity, AC potential distribution, and mitigation measures of the buried pipeline were clarified through field inspection and numerical simulation evaluation. Post-evaluation showed that the pipeline AC interference problem has been solved. Based on this engineering case, the evaluation methods of AC interference intensity of pipelines by high-speed railway and AC transmission lines were significantly different. The numerical simulation calculation has an important role in the reasonable design of dynamic AC interference drainage ground bed quantity and grounding resistance.
