摘要
本文试图利用系统工程原理,解决济宁—兖州矿区的供、排水矛盾。在仔细分析矿区水文地质条件的基础上,建立了水文地质概念模型和相应的数学模型,并应用最优化理论识别了模型的水文地质参数;然后,建立了矿区地下水多目标管理模型,其目标函数为:1)使兖西水源地供水量极大化;2)使岱庄、许厂井田排水费用极小化。采用模糊线性规划法求得了管理模型的最优解,最后通过灵敏度分析和流场模拟,证实了最优解的正确性。
The overall goal of this article is to solve the contradiction between supplying and draining groudwater in the Jining-yianzhou mineral districts by means of the principle of systematic engineering. On the basis of the careful analysis of hydrogeolo-gical conditions in the mineral districts, the writers have established a conceptual model of hydrogeology and its corresponding mathematical model. The hydrogeological parameters of the model have been identified by the optimal theory. Then, a multiple-objective management model of groudwater flow in the mineral districts has been developed. Its objective function is as follows: ( 1 ) to make the water-supply amount maximum in the Yianxi source of water supply field) ( 2 ) to minimize the cost of water draining in the Daizhuang-xuchang mineral field. An optimal solution has been found by using the method of fuzzy linear programming.Finally, by sensitivity and simulating the flowing field, the optimal solution has been proved to be very correct.
