【摘要】 深井水位能够反映地球固体潮体应变、气压变化、地震波等多种应力应变变化。利用天津高村、河南范县和北京洼里井各两年的井水位与气压整点观测值资料进行频谱分析和回归分析,求出了井水固体潮相对于体应变固体潮理论值的振幅比、时间滞后以及含水层系统中井水的气压系数。初步确定了气压系数与气压变化的频率和气压基值的关系,并对含水层系统中井水的特点给以定性的物理解释。这对于研究含水层性质及水位资料的数据处理是一项基础性工作。更多还原

【Abstract】 Thee water level in deep well can reflect variant stress-strain variations which are caused by tidal dilatation, air-pressure, seismic waves and so. on. Using the hourly observed data of water level and barometer from Gaocun, Tianjin City, Fanxian, Henan Province andWali, Beijing City, the spectral and regressive analyses have been made. The length of the data is two years for each well. The amplitude ratio and the time delay of the observed water level with respect to the theoretical values of the tidal dilatation as wall as the barometric coefficient of the well level in aquifer system have been obtained simultaneously. The analysis results have primarily given the relationship between the barometric coefficient and the frequency, base value of the air-pressure. Counting in the feature of the well in aquifer system, the qualitatively physical interpretation is given. The research of the characteristics of the barometric effect is a fundamental work to the study of the aquifer’s property and the data process of the water level.更多还原
