| 摘 要： | 据 Dupuit 假设，地下水渗流场中潜水位、测压水位线的斜率可反映该点水力梯度值的大小，其值随着含水层厚度、含水层透水性能等而发生变化，分析了其变化规律及其原因，对分析复杂的渗流场中地下水的运动具有较为重要的意义。

| Abstract: | The rate of phreatic water level and piezometric level in groundwater seepage field is supposed to reflect the hydraulic gradient value according to Dupuit suppose.It changes with the thickness and the per-meability of aquifer,and so on.This paper analyzes the changes and the reasons of the gradient value.It has a very important significance for the analysis of complex groundwater seepage field. |
