摘　　要：燃气管道的安全运行事关环境、资源浪费及群众人身财产安全等问题,因此埋地燃气管道泄漏后迅速准确地检测出漏点位置十分重要。本文分析了氖气作为示踪剂在管道泄漏检测中的优点,并通过泄漏检测实验验证了氖作为示踪剂的有效性和可行性。针对现场浓度检测数据随机波动大的问题,本文提出了二次拟合的数据处理方法。最后通过实际开挖对比,验证二次拟合法确定的漏点位置与实际泄漏位置一致,从而证实了二次拟合法的有效性和优势。The safe operation of gas pipelines is a matter of to the environment,waste of resources and the safety of people’s personal property,so it is very important to quickly and accurately locate the leak position after for buried gas pipeline.This paper analyzes the advantages of neon as a tracer in pipeline leak detection and verifies the effectiveness and feasibility of neon as a tracer through leak detection experiments.For the problem of large random fluctuations of field concentration detection data,this paper proposes a data processing method of secondary fitting.Finally,through actual excavation comparison,it is confirmed that the leak location determined by the quadratic fitting method is consistent with the actual leak location,thus verifying the effectiveness and advantages of the secondary fitting method.
