摘要
本文建立了潮汐效率与越流共同作用条件下承压水头动态的数学模型.利用复变函数的基本原理,考虑到地下水流动的连续性,推导出了相应的承压水头动态公式.以此动态公式为基础,提出了直接利用承压水头的潮汐动态来确定延伸到海底的含水层长度(边界条件)的计算方法.最后结合广西北海市的地下水头长观资料,对上述方法进行了应用和分析研究.
In this paper, a mathematical model of the confined groundwater level flue -tuations is built on the condition that the level fluctuations are caused by the sea-tide through tidal and leakage effects. The solutions for the subsea and inland aquifers are derived by complex transformations. The continuity of flow between the subsea and inland aquifers is taken into account and leads to a general formula for the groundwater level fluctuations. Then the confined aquifer boundary is determined. The method is based on the theory that the length of extension of confined aquifer is a function of the natural tidal regime of the confined water level. So the actual length(boundary) can be computed by comparison of the observed groundwater level fluctuations with those computed by the formula under various assumptions concerning the length. The method is applied first to the confined aquifer in the Beihai pennisula, Guangxi.
