| 中文摘要: |
| 以非完整河(渠)旁完整井列抽水的理想化实际模型为基础，建立起该模型的三维稳定渗流数学模型，采用有限差分法求解了各种不同情况下此模型的数值解。根据求解结果认为，在非完整河(渠)旁抽取地下水会产生越河(渠)渗流问题，河流(渠)的宽度、河流(渠)的完整性以及河底弱透水层的渗透性都会对越河渗流问题产生重要的影响，对这类问题的求解应采用三维渗流数学模型 |

| Abstract By using an ideal model of pumping groundwater near an incomplete river,the authors developed a 3-D steady state mathematical model for the problem.On the basis of solving the model using finite difference method,the authors concluded that pumping near an incomplete river may cause groundwater flow from the other side of the river into the pumping side.The width,completeness of the river and the permeability of the river bed layer will strongly affect this kind of groundwater flow.Groundwater flow problem under such circumstance should be simulated by 3-D mathematical model. |
