摘要
通过一个使用磁法探测技术对遗失在水下的铁磁性施工器件的快速探测定位的应用实例。介绍了如何使用地面磁力仪在水域勘察施工的方法;如何识别水上船只对磁法测量的干扰影响;利用磁法测量资料对水下场源位置判定的方法;对比分析了对遗失在水下的铁磁性施工器件位置的现场判断、资料处理解释后的认定与探摸验证的结果。通过总结,笔者认为磁法探测技术是寻找水下磁性物体的最有效的方法。
This paper introduces the operation of land magnetic detection used in water area to search for ferromagnetic body lost through an actual case; expresses the procedure of recognizing interference caused by vessels back and forth from interesting magnetic anomaly and shows the location to magnetic body dropped occasionally underwater during operation on water,and finally gives the result of determination and salvage,after data processing,analysis to the measured magnetic anomaly. It is believed that magnetic survey is the effective technique to search for ferromagnetic objects underwater.
