摘　　要：采用磁法探测未爆炸弹具有快速、定位准确和成本低廉的优势。探测UXO(Unexploded Ordnance)对于国家经济建设和保障人民生命财产安全的意义重大,本文介绍了磁法探测UXO的原理和磁法探测炸弹有效深度模拟试验的工作情况,经过分析得出磁法探测不同规模炸弹的有效深度,对试验中出现的磁化反常现象进行分析和讨论。To detect unexploded ordnance （UXO）, it has proved that magnetic survey has advantages of promptness, accuracy and low cost. UXO detection for the state＇s economic development and the safety of life and property to people is of great significance. This article briefly discusses the magnetic methods and principle to detect UXO, and introduces the modeling experiment of the effective detection depth of magnetic survey probes into UXO. It results in the valid depth of magnetic method probing into the different scale shell. During the trial, the phenomenon of magnetization direction abnormal raises our interest, so we also made some necessary discussions about it.
