永安地震台TJ-Ⅱ型体应变仪观测资料干扰分析
|
摘要
通过对永安地震台TJ-Ⅱ型钻孔体应变仪观测资料分析,总结日常观测可能遇到的多种干扰因素。从自然、仪器自身、人为干扰、外界环境等于扰因素的典型表现,加深对非地震前兆的干扰识别,以便更好地排除干扰,提高仪器观测资料质量。
Based on the TJ-Ⅱ borehole strain observation data analysis at Yong'an Seismic Station,many interference factors that the daily observation process may encounter are summed up.From natural factors,instrumental factors,disturbance factors,environmental factors,and other aspects of the interference factors of typical performance,the understanding and identification of non-seismic precursor interference are enhanced,in order to better eliminate such interference and improve the instrument observation data quality.
