基于磁梯度法的深埋管线探测技术研究
摘要:针对一般管线探测仪等不能解决的深埋管线探测问题,建立了水平圆柱体磁异常及磁梯度异常正演模型,通过对水平金属管道的磁异常垂向剖面图和磁梯度异常垂向剖面图对比,给出确定管线埋深的判别标志-"s"的拐点,且在实际应用中取得了理想效果。
Abstract:General pipeline detectos can not solve deeply buried pipeline detection problem. A horizontal cylinder of magnetic anomalies and the magnetic gradient anomalies forward model are established. Through horizontal metal pipes magnetic anomaly vertical cross-sectional view of the magnetic and gradient anomalies vertical cross-sectional view of contrast. The "s" inflection point is of tained to determin pipeline depth discriminant flag, and in the practical application of the desired effect.
