摘　　要：介绍了超声导波检测埋地管道的特点和应用。重点描述天然气输气站场的在线超声导波检测过程和结果的分析诊断。开挖验证结果与分析诊断结论相符。实践证明,长距离超声导波检测技术是站场快速检测的有效方法,能够在最少开挖和最少剥离防腐层的情况下,全面检测埋地输气管道。检测和分析结果准确可靠,能够作为修复的依据。Ultrasonic guided wave testing is widely used for the inspection of buried pipelines at present.The characteristics and application of inspection were introduced.As an example,pipelines in gas station were tested on-site and the testing result reliability was verified by excavation.Data analysis method was developed to analyze the inspection data.Comparison results showed that the ultrasonic guided waves could make it reality to test on-site quickly,and had wide prospect.
