Analysis of anti-interference effect of magnetic field observation system at Luanxian Seismic Station
摘要
Abstract
The interference of near field ferromagnetic material (farmland cultivation,infrastructure,etc.),DC power supply interference (high voltage direct current transmission,earth resistivity observation and so on) are the main ways of ground magnetic observation.In this paper,the installation ofborehole geomagnetic observation system at Luanxian Seismic Station is introduced.An anti-interference test of borehole observation has been carried out.It is verified that the borehole observation of geomagnetic field can inhibit the short-range ferromagnetic substance interference,but can not inhibit the interference of DC power supply (by a certain distance,avoid solving).This analysis results provide the technical reference specifications and basis for future selection of earthquake monitoring means.关键词
