地电阻率观测中地铁干扰剔除方法
Further research of the methods on earth resistivity observation with eliminating the interference of subway
摘要
Abstract
The metro electromagnetic interference signal is detected by analyzing the data of earth resistivity which is observed at Jiangning, Qingguang and Tongzhou seismic stations. Two methods are used here to eliminate interference. One method is using the average value observed at night to replace the data of 24 hour average value. The other is using the average value of different periods at different stations. At present, the interference of seismic stations has become more and more serious because of the complicated situation of station relocation and reconstruction, the methods provided here can solve interference problem with deifnite regularity.关键词
