| 摘 要： | 为了准确地研究低渗介质中地下水污染问题,在充分考虑地下水在低渗介质中渗流时存在启动压力梯度和动边界的基础上,建立了低渗介质中地下水污染和地下水渗流的耦合数学模型。采用有限差分法和混合有限分析法对耦合模型进行数值求解,并分析了启动压力梯度对地下水污染浓度的影响。结果表明启动压力梯度对地下水污染浓度的分布有着重要的影响,在研究低渗介质中的污染问题时不容忽视。

| Abstract: | In order to study the issues of groundwater pollution,on the basis of considering starting pressure gradient and moving boundary in low permeability pore,the authors has established the coupling mathematic model of groundwater pollution and seepage.The finite difference method is used to solve the coupling model,and the influence of starting pressure gradient on the distribution of groundwater pollutant concentrations is analyzed.The results indicate that the starting pressure gradient has an important influence on the groundwater pollution.It cannot be ignored when the issues of groundwater pollution in low permeability pores are studied. |
