| 摘 要： | 在三台山森林公园建设过程中,宿迁地震台地磁观测受到严重干扰。分析了对地磁场造成干扰的主要因素,通过对比干扰前后的地磁场观测数据,运用矢量合成的规则,计算出干扰磁场的7个要素,再使用IAGA推荐的理论公式对建筑中铁磁性材料造成的干扰进行计算,得到铁磁性材料产生的干扰数据情况。

| Abstract: | During the construction of the Santaishan Forest Park,the magnetic observation of Suqian Seismic Station was seriously disturbed.This paper analyzes the main factors causing interference on geomagnetic observation data.By using the contrast before and after interference of magnetic field,and the rules of vector synthesis,the 7 elements of the interference magnetic field are calculated.Then by using the theoretical formula recommended by IAGA tocalculate the disturbance data generated in ferromagnetic materials,it is concluded that the disturbance of observation environment is a common phenomenon. |
