| 摘 要： | 利用淋溶试验,模拟天然降雨,分析煤矸石路堤填筑过程中给高速公路沿线地下水造成的污染,获得了大量真实可靠的数据,得出了煤矸石淋溶液中无机盐是是造成高速公路沿线地下水污染的主要原因.并基于多孔介质流体力学和溶质运移动力学建立了描述微量元素在土壤-水环境系统中迁移的数学模型,并利用该模型对煤矸石淋溶微量元素在道路沿线土壤-水环境中的迁移规律进行了模拟分析,预测了污染物浓度变化规律及分布特征.图5,表2,参12.

| Abstract: | The leaching tests simulating the natural raining were used to analyze the pollution made by coal gangue to the ground water along the coal gangue embankment of highway under construcyion. It is concluded that the salts in the overflow water of waste damp is the primary pollution source for the ground water along the highway. Based on the porous media fluid mechanics and solute transport theory,the mathematical models were developed for describing the transformation of the trace elements in groundwater aquifer. This model is applied to simulate the concentration distribution. 5figs.,2tab.,12refs. |
