宽城地震台水管倾斜仪端点一致性分析

The endpoints consistency analysis of water tube tiltmeter at Kuancheng Seismic Station

选取宽城地震台2008—2013年DSQ型水管倾斜仪观测数据,重点分析仪器运行状况较好的2011年度水管仪端点观测数据,对水管倾斜仪两端点一致性进行相关性分析。结果表明:宽城地震台水管倾斜仪同一分量两端点的固体潮形态、相关系数、方差及均值、潮汐参数无显著差异,相关性较高,产出的数据稳定、可靠。

In this paper, through the analysis of the DSQ water tube tiltmeter observational data at Kuancheng Seismic Station from the year 2008 to 2013, focusing on the observation data which had better operation conditions of the instrument in the year of 2011. the consistency of endpoints of the water tube tiltmeters at Kuancheng Seismic Station is analyzed. It is found that the two endpoints of the same component had the same solid tide, the highly correlation coefficient, while the variance and mean and tidal parameters had no significant difference. The observation data of the instrument is stable and reliable.
