巴里坤石英水平摆倾斜仪观测数据干扰分析OA

Based on continuous observational data from the quartz horizontal pendulum tiltmeter at Balikun Seismic Station from 2019 to 2025,this study systematically tracks and identifies several typical interference patterns.By analyzing the morphological characteristics and variation rules of various interference curves,the annual variation elimination method is used to quantitatively assess the effects of environmental factors such as rainfall and air pressure,and to eliminate interference from the natural environment,manual operation,and instrument calibration.The results show that:① The annual variation amplitude of the EW component is 4 886.73″,which is significantly higher than 623.22″ of the NS component;② The rainfall response coefficient is 151.01″/mm for the NS component and-62.74″/mm for the EW component;③ The barometric pressure efficiency coefficient is 5.34″/hPa for the NS component and-4.38″/hPa for the EW component.The research results can provide a reliable basis for judgment in daily data processing,help improve data quality,and reduce misjudgment.
