半承压含水层中稳定流动的淡地下水与停滞的咸地下水交界面是由建立在含水层中水平流线的裘布衣近似和交界面是清晰的假设基础上的二阶非线性常微分方程来描述的。引入简化的无量纲变量分别代替交界面的深度和距离。提出了近似解,讨论了它的精确度。对接连的几个围圩抽取淡地下水和具有不连续分布的地下水文常数的纵剖面提出了计算结果的实例。
Semi-confined aquifers in the stable flow of light groundwater and stagnant salty groundwater interface is established by the formation of the horizontal flow line in the aquifer streamlined approximation of the furrows and the interface is clear assumptions based on second-order nonlinear ordinary differential equations describe. The introduction of simplified non-dimensional variables instead of the depth and distance of the interface. An approximate solution is proposed and its accuracy is discussed. A few examples of the results of the calculation of longitudinal groundwater profiles extracted from the contiguous gullies and groundwater hydrographs with discontinuities are presented.
