常熟地震台DSQ水管倾斜仪干扰分析
|
摘要
对常熟地震台DSQ水管倾斜仪3年多的资料进行初步分析,雷电降雨、气温突变、气压变化会使观测数据发生畸变,雷电干扰时观测数据产生台阶、脉冲,甚至仪器故障、水管换水会使观测数据产生较大幅度漂移,伸缩仪标定时的检修也会对水管仪产生干扰,停电后恢复供电会使数据产生漂移现象。
More than 3 years of observation data of DSQ water tiltmeter at Changshu Seismic Station are preliminarily analyzed.The results show that the interference factors,such rainfall, temperature mutation and the change in pressure will cause the distortion of observation data.Lightning will generate step or pulse interference in observed data.Equipment failure or changing the water pipes will have a more substantial shift of observed data.The calibration and overhaul of extensometer also interferes the water meter observation.The resume of power supply will generate the tail drift in observed data.
