DYNAMIC CHARACTERISTICS OF WATER TEMPERATURE FOR YIMEN WELL AND CAUSE ANALYSIS
The water temperature observation data of Yimen Well over the past 30 years is taken as the research object,and various interference factors recorded during the water temperature observation are systematically col-lected and organized.The reflecting earthquake ability of water temperature of Yimen Well is analyzed,and the dynamic change characteristics of water temperature and the formation mechanism are summarized.The results show that the daily variation of water temperature of Yimen Well is fluctuating,and the difference in daily varia-tion shows a trend of decreasing year by year,and the dynamic trend of water temperature over the years is a small-oscillation and slow-ascending trend;the environmental interference factors of the site for the water tem-perature of Yimen Well are small,and the main interference factors for the water temperature are observation sys-tem faults and human interference.The water temperature observation system faults are mainly instrument faults and power supply faults,manifested in the form of declining and missing data.The human interference mainly involves installation,calibration of instruments,and sampling,manifested in short-time"V"shape or step change;If the water temperature in the Yimen County well turns or accelerates during the rise of the small am-plitude oscillation,the change may be caused by the tectonic activity in the adjacent area;the co-seismic varia-tion of the water temperature of Yimen Well shows a rapid-declining and slow-rising process.
