Abnormal determination of north-south component of water pipe tiltmeter at Wuzhishan station
The north-south component of the DSQ water pipe tiltmeter at Wuzhishan station has been tilting southward continuously since May 2017. We eliminate various reasons such as the deformation observation system of the Wuzhishan station, the temperature of the cavern, the auxiliary observation data and t...

| description | The north-south component of the DSQ water pipe tiltmeter at Wuzhishan station has been tilting southward continuously since May 2017. We eliminate various reasons such as the deformation observation system of the Wuzhishan station, the temperature of the cavern, the auxiliary observation data and the changes in surrounding environmental factors, and use the methods of the evaluation and analysis of the quality of the ground tilt observation data and the recognition of digital precursory anomalies. Combined with GPS and gravity field changes, it is concluded that the south tilt of DSQ water pipe tiltmeter at Wuzhishan station may be a normal regional background change trend, not a precursor anomaly. |
