Abstract
In order to better protect the observation environment of the seismic station,this paper proposes a method for analyzing the interference sources of the seismic station based on the actual work process,aiming at the lack of systematic methods and insufficient legal level in the existing determination of interference sources.Firstly,based on the analysis of the degree of interference to the station and the establishment of working basis,this paper studies the time,space,intensity and frequency characteristics of interference signals.Then,according to the requirements of norms and interference characteristics,the investigation scope is narrowed and on-site investigation is conducted to eliminate non-interference sources one by one.Finally,the main interference sources of the station are determined by analyzing the correlation between the remaining interference sources and noise intensity.This method includes legal requirements,station data analysis and investigation work points.It is proposed that the interference sources of seismic stations should meet three key indicators of characteristics,exclusivity,and relevance.Good practical application results have been achieved in the planning of seismic and geophysical station networks,earthquake observation environment protection,and station construction site selection in Wuhan.关键词
