河北区域DSQ型水管倾斜仪端点一致性分析

Analysis on endpoint consistency of DSQ-type water pipe inclinometer in Hebei area

河北区域地震前兆台网6个地震台站配备DSQ型水管倾斜仪进行地倾斜观测,选取2009—2016年记录的观测数据,对水管倾斜仪两端点一致性进行相关性分析。结果表明:各台站水管倾斜仪同一分量2个端点的相关系数、方差及均值、潮汐参数无显著性差异,相关性较高,表征产出的数据稳定、可靠。

There are 6 seismic stations equipped with DSQ water pipe inclinometer in Hebei regional earthquake precursor network for ground tilt observation. The observation data recorded from 2009 to 2016 which were selected to analyze the correlation between the two ends of the water pipe inclinometer. The results show that there is no significant difference in correlation coefficients, variances, mean values, and tidal parameters at the two ends of the same component of each station’s water pipe inclinometer. The correlation is high and the output data are stable and reliable.
