数值法与解析法在地下水溶质运移中的应用分析

Application of numerical method and analytical method in groundwater solute transport

本文以赣西平原地区某垃圾填埋场地下水溶质运移模式为研究对象,选用Visual MODFLOW的MT3DMS模块的数值法和一维稳定流动二维水动力弥散问题的解析法,对该垃圾填埋场的铬(六价)污染物在非正常工况下的迁移过程及污染范围进行预测,对比该两种方法在分析赣西平原地区地下水溶质运移中的区别,以研究出更适合于该地区的地下水溶质运移分析方法,为后期该地区开展地下水溶质运移研究的方法选用提供参考。

This paper took the groundwater solute transport model of a landfill site in Ganxi plain as the research object,forecasted the migration process and pollution range of Cr^(6+) pollutants in the landfill site under abnormal conditions by using the numerical method of MT3DMS module of Visual MODFLOW and the analytical method of one-dimensional steady flow two-dimensional hydrodynamic dispersion problem,and analyzed the differences between the two methods in groundwater solute transport in Ganxi plain,to study a more suitable analysis method of groundwater solute transport in this area,and provide a reference basis for the selection of groundwater solute transport research methods in this area in the later stage.
