| 摘 要： | 均质含水层中的自由水面(潜水)问题,虽然有各种各样的分析解和近似解,但对非均质条件还缺乏合理的解答。目前虽可采用虚构流网的概念相当准确地计算侧向补给情况的潜水井流量,但由于这种方法不能计算渗流场的水头分布,仍不易把它引用到不稳定渗流问题中去。

| Abstract: | Finite element technique is utilized to analyze the steady flow toward a completely penetrating unconfined well in a 2-layered porous material. A comparison of solutions for an idealized problem, obtained by using both finite element method and fictitious flow net concept, indicates they achieve approximately the same degree of accuracy. A laboratory application of the two methods shows that finite element procedure provides more satisfactory solution than the other.The primary advantage of finite element approach to digital modeling of ground-water problems is the flexibility in application, it seems certain that this approach may be readily adapted to solutions of aquifer systems with arbitrary geometry and material non-homogeueitv. |
