通过分析滨海含水层中观测孔的水位动态资料,确定含水层的水力性质和某些参数,或推测含水层在海底的延伸长度和露头处是否存在覆盖层,是水文地质学家一直很感兴趣的问题之一。文中充分分析了广西北海半岛滨海地区水文地质条件,将研究区第一个承压含水层系统概化为具有上覆弱透水层越流和含水层海底露头覆盖层的垂向三层结构的不稳定流模型。应用该模型的解析解对广西北海半岛滨海含水层系统的观测数据进行了分析,拟合效果很好,并利用最小平方罚函数法估算了研究区含水层的参数。
It has been of interest to hydrogeologists to analyze the hydrological characteristics of aquifers in the coastal aquifer and to determine their hydraulic properties and certain parameters, or to predict the extent to which the aquifer extends beyond the seafloor and the outcrops One of the problems. The paper fully analyzes the hydrogeological conditions in the coastal area of Beihai peninsula in Guangxi, and generalizes the first confined aquifer system in the study area to a vertical three-layer structure with overlying aquifer over-flow and aquifer submarine outcrop cover Stable flow model. The analytic solution of this model is used to analyze the data of the coastal aquifer system in Beihai Peninsula, Guangxi. The fitting results are good and the parameters of the aquifer in the study area are estimated by the least square penalty method.
