| 摘 要： | 介绍了在水中进行高精度磁测的工作方法 ;指出探查水中的钢铁构件时 ,只须考虑磁异常的存在、位置 ,而无须考虑磁异常的符号 ;通过资料处理 ,消除了桥体磁场的影响 ,划分出局部磁异常 ,推断出的失落在水中的钢梁 (轨 )构件位置与实际符合较好。

| Abstract: | This paper introduces the method of high magnetometry using in water. Pointing out that existing and position of magnetic anomalies must be only cosidered when exploring iron and steel structural frames, while without regard to the sign of magnetic anomalies. The effects of magnetic field about the bridge body are removed and the local magnetic anomalies are located after data processing. Finally, the positions of steel beans (rails) under water are deduced, and which is well conformed with actual condition. |
