摘要
为比较准确地模拟二重孔隙介质地下水溶质运移 ,本文依据二重孔隙介质法 ,分别对孔隙岩块和裂隙介质建立相应的溶质运移模型 ,将孔隙岩块视为作用于裂隙介质的源或汇 ,对反映岩块和裂隙介质之间物质交换的耦合项进行了数学推导。应用本文方法在济南地区建立起二重孔隙介质溶质运移模型。研究结果表明 。
In order to simulate solute transport accurately i n fractured porous media, by using the dual porosity media method, a rock mass m odel and a fracture model are set up in this paper, in which the rock mass is re garded as a source or sink of the fracture media. The coupling term reflecting m ass exchange between the rock mass and the fracture media is derived. A model wi th a dual porosity medium is established for the Jinan area. The results show that this method can better reflect the strong conduction of solute through frac tures and the strong storage capability of rock mass for solute.
