乾陵地震台地倾斜观测运行效能分析

对乾陵地震台2019年7—12月VP型垂直摆倾斜仪和DSQ型水管倾斜仪观测数据进行系统分析，对比研究2套仪器在固体潮记录、数据连续性、观测精度、日均值变化趋势相关性和映震能力等方面的差异，结合乾陵地震台地质构造、台基岩性和仪器自身差异等分析产生差异的可能原因，并分析2套仪器在不同方面的优势。

Analysis of operation efficiency of ground tilt observation at Qianling Seismic Station

Based on the systematic analysis of the observation data of VP vertical pendulum tiltmeter and DSQ water-tube tiltmeter at Qianling Seismic Station from July to December in 2019, the differences between the two sets of instruments in the aspects of solid tide record, data continuity, observation accuracy, correlation of daily average variation trend, and earthquake reflecting ability are compared. Combined with the geological structure, lithology, and instrument differences of Qianling station, this paper analyzes the possible reasons for the differences and analyzes the advantages and disadvantages of the two sets of instruments in different aspects, so as to provide a reference for future research and development of instruments, as well as the analysis and research on the observation and prediction efficiency of Qianling station.
