摘　　要：为解决粤西地区滩涂管道不均匀沉降引起的管道应力集中导致管道失效风险增加的问题,建立了磁偶极子模型,获取了不同轴向应力条件下的磁梯度模量。通过比对检测过程中的检测距离信息,实现了不同轮次间检测数据的对齐,形成了埋地钢质管道非接触式应力动态监测方法,实现了不均匀沉降风险管段的应力动态监测,有效保障了管道的正常运营。针对某埋地X60管道开展了动态磁应力监测,评估了其应力变化趋势,并制定了应对措施,具有工程意义。To solve the problem of increasing the risk of pipeline failure caused by the concentration of pipeline stress caused by the differential settlement of pipelines in mudflat in western Guangdong,a magnetic dipole model was established and the magnetic gradient modulus under different coaxial stresses was obtained.By comparing the detection distance information in the detection process,the alignment of the detection data between different rounds was realized,and a non-contact stress dynamic monitoring method was formed for the buried steel pipeline,which realized the stress dynamic monitoring of the pipeline segment at risk of differential settlement,and effectively guaranteed the normal operation of the pipeline.The dynamic magnetic stress mo-nitoring was carried out for a buried X60 pipeline,the stress variation trend was evaluated,and the corresponding measures were formulated,which has engineering significance.
