摘要
作者运用有限单元法,根据变化的历史开采布局和污染演化趋势,建立了水量水质耦合模型,对岩溶水资源进行了数值模拟评价。在此基础上,以现状开采量和历史水质污染的演化趋势为基准,对未来10年的岩溶水水位水质进行了预测,预测结果表明:在2010年,部分地区的氯离子浓度超出了饮用水标准,大部分地区的总硬度严重超标。
According to the historical mining layout and the trend of contamination evolution,the authors established a coupling model of karst water quantity and quality by applying the finite element method.The karst water resources in Taian city were simulated and evaluated.On this basis of the present mining quantity and historical evolution trend of karst water contamination,the karst water level and quality for the next decade were predicted.The result shows that the concentration of the chloride ion in some parts of the area will exceed the standards for drinking water.Particularly,the concentration of the total hardness in large parts will seriously exceed the standard for drinking water.
