摘　　要：地磁台建设磁性跟踪测试工作很重要,通过对跟踪磁测中发现的一个异常现象的分析,计算了不同重量、距离的铁磁性物质对磁房建筑场地磁场的影响,讨论了排除施工现场磁性干扰的一些办法,并得出各种重量铁磁性物质与磁房建筑物的安全距离,还讨论了地磁台部分建筑材料的选择问题。Tracing survey of Geomagnetism is very important in the construction of geomagnetic station. In this paper, it is calculated of the effect of ferromagnetism matter with different weight and distance to the geomagnetic building, through the analysis of an abnormal phenomenon that discovered in tracing survey. Some methods to eliminate the geomagnetic disturbance in the scene of constructing are discussed. In this paper, it is calculated of the safe distance of ferromagnetism matter of different weights to the geomagnetic building. The choice of building materials for geomagnetic station is also discussed.
