摘要
从应用频率域电磁法探测地下金属管线的基础理论出发,在一定前提条件下将地下管线敷设模型简化,并分析简化模型在地面产生的磁场的分布特征。利用这些特征了解多根金属管线问题的本质,通过反演的手段尝试解决近距离平行管线探测的问题。
Based on the basic theory of frequency domain electromagnetic method for detecting underground metal pipelines,the laying model of underground pipelines is simplified under certain conditions,and the distribution characteristics of magnetic field generated by the simplified model on the ground are analyzed.These features are used to understand the nature of the multi-metal pipeline problem,and using the inversion method to solve the problem of closely-spaced par allel pipeline detection.
