摘要
为提高海底管线探测的效率,从磁偶极子模型出发,通过磁矩的轴向分解及其磁场的矢量合成,并考虑地磁背景场影响,提出了一种计算水下管线磁场的数学模型,通过仿真计算三种不同走向管线的磁场分布并与实测数据比对,证明所建模型是正确的。
In order to detect underwater pipeline effectively, based on magnetic dipole model, the article presents a method for calculating magnetic field of underwater pipeline by separating a magnetic moment into three components in direction of coordinate-axis, and combining the field vectors meanwhile considering the earth＇s magnetic background influences. It is proved true by comparing simulated three different directional pipelines magnetic fields with actually surveyed results.
