宝昌地震台VP型宽频带垂直摆倾斜仪干扰因素分析
|
摘要
选取2014年、2016年5月、2017年1—9月宝昌地震台VP型宽频带垂直摆倾斜仪观测资料,针对观测山洞湿度、雷电、人为因素等干扰,与正常时段光滑、噪声低的正弦固体潮观测曲线进行对比分析,通过对干扰因素进行分析与排除,可提高形变观测资料质量,为准确识别震兆异常提供参考。
In this paper, the observation data of vertical pendulum inclinometer at the baochang seismic station in 2014, May 2016 and January to September 2017 were selected. Aiming at the problem of observation data of the station VP inclinometer affected by the factors such as humidity, lightning and human disturbance, carry out comparative analysis of observation data of interference observation data and smooth, low-noise sinusoidal tide curve in normal period. Comprehensive analysis believes that the quality of deformation observation data has improved by analyzing and eliminating interference factors, and provide a reference for accurately identifying earthquake anomaly images.
