摘　　要：选取乌兰浩特地震监测中心站2015-2022年伸缩仪观测资料,分析自然环境、人为因素、场地环境等干扰因素对观测数据造成的变化,其干扰特征主要表现为缺记断记、数据突跳、台阶、曲线粗糙、毛刺增多、固体潮畸变等。研究结果可为该站伸缩仪仪观测数据干扰识别及映震异常特征分析提供参考。Based on the extensometer data from 2015 to 2022 at Ulanhot Seismic Monitoring Center Station,the interference factors of the natural environment,human factors,and site environment on the observation data are analyzed,in which the interference characteristics are mainly manifested as missing records,data jumps,steps,rough curves,increased burrs,solid tide distortion,and so on.The research results can provide a reference for the interference identification of extensometer observation data and the analysis of earthquake anomaly characteristics.
