摘　　要：在与资源勘察和地质调查不同的工程勘察、考古调查等领域,其探测的目标物体常常是炸弹、沉船、古墓葬等由人类制造和建筑的人文物体,由于其生成环境和生成条件与矿床、构造完全不同,因此在对这一类场源进行磁测资料处理时,必然与矿产调查时有所不同。结合模型实验讨论和总结了上述类目标体在化极处理时的差异;讨论了如何根据人文目标体的特点选择参数,并对评价标准进行了总结;另外,还通过勘察工作实例对从模型实验的正反演中得到的认识和评价标准进行了验证。研究得到了比较完美的应用效果,证实和表明了提出的化极处理时参数选择原则和评价标准的可行性和可靠性。Unlike resource survey and geological survey,the detecting targets are usually some man-made objects such as bombs,shipwrecks,tombs and so on in the field of engineering investigation and archaeological investigation.It will inevitably have some differences with the mineral survey when the magnetic data of this field source are processed for their generating environment and conditions are different with those of mineral deposit and geological structure.This paper discusses and summarizes the differences of reduction to pole processing from the fore-mentioned target objects;discusses the parameter selectionmethod on the basis of the man-made objective features and summarizes the evaluation standard.Moreover,this paper verifies the evaluation standard which is summarized from the forward and inversion simulation of the model test by a living investigation example.The relatively ideal application effect certifies that the evaluation standard and the parameter selection principle of reduction to pole processing are feasible and reliable in this paper.
