摘　　要：2015年以来,我国为加快推进地震预警技术体系建设,在全国范围内启动“国家地震烈度速报与预警工程”建设工作,其中在大同、朔州新建地震预警基准、基本站33个,新建一般站146个。为深入了解新建基准、基本站运行状况,本文对各站点试运行以来运行情况和台基噪声、地震记录及地震预警触发等情况进行分析。结果显示,各站点运行状况良好,运行率呈稳定上升趋势,延时率呈稳定下降趋势,站网总体观测环境噪声、波形记录、地震预警触发良好,山西地区地震预警初见成效。Since 2015,to accelerate the construction of earthquake early warning technology system,China has launched the"National Earthquake Intensity Rapid Reporting and Early Warning Project"nationwide.Among them,33 new earthquake early warning benchmarks and basic stations have been built in Datong and Shuozhou,and 146 new general stations have been built.To gain a deeper understanding of the operation status of the newly built benchmarks and basic stations,this article analyzes the operation status,base noise,earthquake records,and earthquake early warning triggers of each station since its trial operation.The results show that the operation status of each station is good,with a stable upward trend in operation rate and a stable downward trend in delay rate.The overall observation environment noise,waveform recording,and earthquake warning triggering of the station network are good,and the earthquake warning in Shanxi region has achieved initial results.
