摘要:
将宽城地震台地倾斜观测和气压观测数据,通过小波变换分析提取气压对地倾斜观测的干扰时段,再对气压干扰时段观测数据进行线性拟合去趋势、别尔采夫滤波获得观测数据的日漂移信息,最终获得地倾斜观测和气压观测的相关系数,通过线性拟合进行气压干扰的排除研究。结果表明:宽城台地倾斜观测与气压观测具有正相关性,通过此方案对地倾斜观测受气压干扰的观测数据进行干扰排除,可以取得较好的效果,提高观测数据可靠程度。
Abstract:
Based on the data of ground tilt observation and air pressure observation at Kuancheng Seismic Station, this paper analyzes and extracts the interference period of air pressure to ground tilt observation by using wavelet transform method. Then,the daily drift information of the observation data is obtained by linear fitting detrending and Perstev’s filtering during the air pressure interference period. Finally, the correlation coefficient between ground tilt observation and air pressure observation is obtained,and the air pressure interference is eliminated by linear fitting. The results show that there is a positive correlation between the ground tilt observation and air pressure at Kuancheng Station. By using this scheme to eliminate the interference of the observation data of the ground tilt observation interfered by the air pressure, a better effect can be obtained and the reliability of the observation data can be improved.
