银川基准台SQ-70D水平摆观测数据干扰分析

Analysis of the Observed Data of SQ-70D Horizontal Pendulum Tiltmeter at Yinchuan Seismic Station

石英摆倾斜仪是监测地球固体潮汐的重要手段之一,通过对银川基准台小口子观测站的SQ-70D石英水平摆倾斜仪数字观测资料数据进行分析,排除干扰因素,客观的分析曲线的变化趋势,发现特征,以便在日常分析处理中排除各类干扰因素,如自然环境干扰、人为干扰和调零标定干扰等,争取最大限度的减少不必要的误导,为台站工作人员提供有效的参考实例。

Quartat fiber tiltmeter is one of the most important monitoring ways on tides of the solid earth, this paper conducts data analysis observed by a SQ-70D horizontal pendulum tiltmeter in Xiaokouzi Observation Station of Yinchuan Standard Station in order to eliminate interference factor, to extract effective interference curves, to analyze the curve＇s variation trend objectively and to find out the features for the purpose of eliminating interference factors in daily analysis processing, such as nature environment interference, human disturbance and zeroing calibration interference etc. In that way unnecessary misleading can be reduced farthest and it can provide effective reference examples to the station workers.
