| 中文摘要: |
| 以岩溶大泉集中排泄是北方岩溶泉域地下水的一个重要特征。由于岩溶大泉具有的特性使有限元法用于泉域地下水动态预测遇到困难。本文总结了岩溶大泉的内在规律,分析了有限元计算的具体过程,在此基础上建立了泉水位和泉流量之间的随机模型,并将其作为水量矩阵的一部分偶合到有限元确定性模型中,从而得到确定——随机偶合模型。该模型在济南泉域地下水动态预测中得到了成功的应用。 |

| Karst-spring's concentration drainage is an important feature of guound water within northern karst-spring basin. With the characteristics of the springs, to foreast the development of the spring-basin ground water is difficult by FEM. This paper has summarized the internal rule of the springs and analysed the concrete process of FEM and then established the adjusting modle between water level and flow of the springs. Combining this adjusting molde into the definite molde (FEM), the definite-adjusting combining molde has been established. This molde has been successfully applied to forcast the development of groundwater within JiNan spring basin. |
