Abstract:By analyzing two sets of water temperature equipment in Jingmen well, this paper checks the observation quality of the water temperature of Jingmen well, summarizes the dynamic change characteristics of the water temperature of Jingmen well and various interference factors encountered in daily observation, so as to provide reference for future water temperature observation when such anomalies occur again. The integrity rate of well water temperature data is calculated and the main factors affecting the integrity rate are analyzed. It is considered that the water temperature instrument in Jingmen well has high reliability and can provide reliable data for earthquake monitoring and prediction.
