非达西渗流分析是地下水资源分析与评价的重要内容。系统地分析与总结了岩土体中地下水非达西 (非线性 )渗流的理论与试验规律 ,采用解析分析和数值分析相结合的研究方法 ,对一维、二维非达西渗流进行了求解 ,并与相应的达西 (线性 )渗流解进行了比较。可以看出 ,不能采用线性渗流规律来近似代替非线性渗流规律 Non-Darcy flow analysis is an important part of groundwater resource analysis and evaluation. This paper systematically analyzes and summarizes the theory and experimental rules of non-Darcy (non-linear) seepage of groundwater in rock and soil, and uses one analytical method and numerical analysis to solve one-dimensional and two-dimensional non-Darcy seepage flow , And compared with the corresponding Darcy (linear) seepage solution. It can be seen that the linear seepage law can not be used to approximate the nonlinear seepage law
