摘要
依据GB/T19531.2—2004地震台站观测环境技术要求第二部分电磁观测,及DB/T9—2004地震台站建设规范(地磁台站)相关要求,应用G856质子旋进磁力仪,对拟建设的黑龙江省同江地磁台观测场地,采用30km十字剖面跨度测量和场地200m×200m、100m×100m密跨度方法进行勘选测量,通过对测量结果的分析,给出勘选结论和建议。
In this paper, based on observation of GB/T19531.2-2004 Seismic Stations Technical Requirements for the second part of the Electromagnetic Environment Observation Volumes, and DB/T9- 2004 the Construction of Seismic Stations Specification （geomagnetic station） Requirements, the G856 proton precession magnetometer was applied in the proposed construction of Heilongjiang Province Tongjiang geomagnetic observation sites. With 30kin span of the cross section measurement and venues 200m×200m, 100m×100m close election survey method of measuring span, the measurement results were analyzed, and the survey conclusions and suggerstions were given.
