| 摘 要： | 地下水位气压系数在震前出现异常变化的研究,在地震预测研究中具有积极的作用和现实意义。利用高采样率的数字化资料,采取一阶差分筛选回归分析的方法,对天津地区4口地下水动态观测井的气压系数进行计算分析,并对其与地震的关系进行探讨。研究认为:不同的井孔,由于自身条件及干扰因素的不同,气压系数在震前的异常变化形态及幅度都有所不同;气压系数是随时间和空间而变化的物理量。通过文安5.1级地震震例检验,提出利用气压系数预报地震的可能性,但将之应用到地震监测预报实践中,尚需更多震例检验,并需开展广泛、系统的研究。

| Abstract: | The research on the air pressure coefficient varieties of the groundwater lever before the earthquake has a positive role and practical significance in earthquakes prediction. In this paper, based on the digital observational data of high sampling rate, the pressure coefficients of four observation wells in Tianjin area are calculated and analyzed with first order differ- ence and regression, and their relations with earthquakes are also discussed. We find that the abnormity shape and amplitude of air pressure coefficients are different before the earth- quake, because of the different boreholes, their own conditions and interference factors are different; the air pressure coefficient is physical quantity of variation with time and spatial change. According to test on the earthquake example of Wenlan M 5.1 earthquake, authors proposed the possibility to predict earthquakes using the air pressure coefficient of the water well, but the method applied to the earthquake monitoring and predicting, still needs more earthquake examples and more extensive and systematic research. |
