摘要
对2008~2012年青海省地震局同仁地震台各前兆测项所受到的干扰情况进行了分析,分析结果认为:环境干扰因素主要有西山沟河渗水、气压突变和雷电等;人为干扰因素包括校准、检查、换水、供电线路改造等;观测技术系统干扰因素有供电电源故障、开机和重启仪器、仪器主机(数采)故障等。
Analyzing the interference situation of precursor items at Tongren Station in Qinghai from 2008 to 2012,the result shows that the environment interference factors mainly include the water percolation of Xishan River,pressure mutation and thunder and lightning etc.,the human disturbance factors include the calibration,checking,changing the water,power supply line reconstruction etc.,the interference factors of observation system include power supply fault,startup and restarting the instrument,and the instrument host( data acquisition) fault etc..
