京津冀地区井水温度的数字化观测及其地震前兆监测效能的评估

较为系统的分析了北京、天津、河北地区井水温度观测现状及年、月、日不同层次上的动态特征,及其在相关的地震前兆监测中发挥效能的可能性做了宏观的评估。评估结果表明,74.7%井的水温观测正常运行,58.6%的井在地震中期或中短期的前兆监测发挥效能,67.8%的井在地震短期前兆监测发挥效能,41.2%的井在地震短临前兆监测中有可能发挥一定效能。文中还提出了进一步发挥井水温度观测监测效能的若干建议。

Digitalized well-water-temperature observation and monitoring efficiency evaluation of earthquake precursor in the Beijing-Tianjin-Hebei region

On the basis of systematical analysis of present observational situation and yearly,monthly and daily dynamic behaviors of water temperature at different levels in the Beijing-Tianjin-Hebei region,a macroscopic evaluation of monitoring efficiency is made in this paper.The result indicates that 74.7% of wells run normally.It also indicates that 58.6% of wells in medium-term or medium-and-short-term precursory monitoring,67.8% of wells in short-term precursory monitoring and 41.2% of wells in short-impending precursory monitoring maybe exert efficiency.In this paper,some suggestions are presented to enhance monitoring efficiency for observation of well water temperature.
