ASMWIN在镇江市地下水渗流模拟中的应用

Application of ASMWIN in Groundwater Flow Simulation of Zhenjiang City

随着人口的增长、工农业生产的发展和人们生活水平的提高 ,对地下水资源的需求量不断增加。地下水的运动方式是地下水在岩土空隙中的渗透流动 ,简称渗流。加强对地下水渗流的分析和研究 ,进行地下水资源评价和地下水变化趋势的预测 ,对指导地下水的合理开发利用及确保地下水供水工程安全等是非常重要的。目前 ,地下水水流模拟的研究方法很多 ,分别适用于不同的水文地质条件。作者采用的是德国的ASMWIN软件 ,它对二维地下水水流和污染质运移过程的模拟具有较高的可靠性 ,而镇江市孔隙潜水的水流为二维流动问题。故将该方法应用于镇江市地下水水流模拟 ,研究结果表明 ,该软件操作方便 ,求解结果与实际的水文地质条件高度一致 ,具有广泛的应用前景。

With the increase of the population, the development of the agriculture and industry and the rise of the people's living level, the demand to the groundwater resource is greatly increasing. The moving way of the groundwater is penetrate flow through the gaps in the stratum, namely seepage. It is very important for guiding the rational exploitation and use of the groundwater and ensuring the safety of the groundwater supply project to enhance the analysis and study of the groundwater seepage and evaluate the groundwater resource and predict its changing tendency. At present, there are a large number of methods to analyze the simulation of the flow, which are applicable for different hydrogeological conditions. The one used in this paper is ASMWIN software of German. It is of the rather high reliability to the simulation of the two-dimensional groundwater flow and the mass transport. It is the two-dimensional flow of the porous unconfined aquifer in Zhenjiang City that the method is applied to the groundwater flow simulation. The simulation result shows that the software is easy to be operated and the results of the evaluation are identical to the real hydrogeological conditions, so it will be widely used in the future.
