ANORMALY DETERMINATION ANALYSIS OF WATER PIPE TILTMETER IN LAOYANGHE OBSERVATION STATION OF TENGCHONG SEISMIC STATION
Since the end of January 2023,there have been occasional small steps in the north-south and east-west directions of the DSQ water pipe inclinometer observation curve at Laoyanghe Observation Station of Teng-chong Seismic Station.Through the investigation of the interference factors of this anomaly,it is considered that this kind of step is caused by the glue falling off part of the water pipe inclinometer bowl dissolved in water.The main characteristics of this kind of anomaly are as follows:in the early stage of the anomaly,the observa-tion curve of the water tube tiltmeter occasionally shows a small step;the amplitude and frequency of the steps in the middle and late stages of the anomaly gradually increase.Cleaning up water impurities can reduce the frequency of steps,but it cannot be fundamentally solved.After cleaning the pot body,the water body can be replaced to completely eliminate the steps.
