Abstract The YRY-4 borehole strainmeter at Xiangyang station has been operating steadily from 2007 to July 2020. Since July 2020, due to the small change in compressive strain, the NE component has not changed significantly compared to other components. In daily business processing, it is believed that the data is distorted and the NE component is damaged. This article analyzes the data of each component of the YRY-4 borehole strainmeter at Xiangyang station and concludes that the NE eastern component is not damaged, but there is still a trend of solid tide and annual variation. At the same time, the correlation of surface strain is calculated, and data quality influencing factors and seismic reflection ability analysis are conducted. It can be concluded that the strain components of YRY-4 borehole at Xiangyang station basically meet self inspection and can continue to be observed. The NE component is not damaged.
