地下水位对引潮力响应的初步研究——以各向同性多孔介质弹性理论分析

Preliminary Study of the Groundwater Level Fluctuation Responding to Tidal Force——Using Isotropy Poroelastic Theory to Analyze

本文以多孔隙弹性介质线性孔隙弹性理论为基础,利用含水层系统孔隙压力变化与平均应力之间的线性数学表达式,选择合适时间段的地下水位与理论引潮力资料,计算水位变化对引潮力响应关系的比例系数和相关系数,验证了地下水位对引潮力响应关系较密切,同时提供了符合场地条件下含水层Skempton比例系数的计算方法。

Based on linear poroelastic theory, we use the linear mathematic expression between the pore pressure change and the change in the average stress for well-aquifer system to analyze the observed groundwater level data and the theoretic data of tidal forces. By this way, we can work out the related coefficient and the proportionality coefficient （the Skempton＇s proportionality coefficient of the aquifer） of groundwater level fluctuation responding to the tidal force. The related coefficient shows the groundwater level fluctuation responding to the tidal force is very clear.
