The observation data of long-term stability using the Tai'an DSQ tiltmeter, by analyzing the typical curve interference pressure, typhoon, lightning, rainfall and groundwater environment and meteorological factors on the observation data of water meter, the water tube tiltmeter data changes of different meteorological factors,gives the identification conclusion. The research in this paper can provide a scientific basis for the interference elimination and abnormal identification of DSQ water pipe tilt obser...
