摘　　要：分析与总结了坝基中非达西渗流的理论与试验规律 ,采用理论分析的研究方法 ,对大坝工程坝基非达西渗流模型进行求解 ,计算坝基面渗透压力分布和坝基渗流量 ,并与相应的达西 (线性 )渗流解进行了比较 .可以看出 ,在坝基非达西渗流分析中 ,不能采用线性渗流规律来近似代替非线性渗流规律 .The theoretical and empirical laws for non Darcy seepage in dam foundation are analyzed and summarized. By means of the theoretical solution method, the model for non Darcy seepage through dam foundation is solved to determine the hydrostatic seepage pressure and the seepage flux, which is also compared with the corresponding linear seepage solutions. It can be proved that the non linear seepage law can not be approximately regarded as the linear seepage law in analysis of non Darcy seepage through dam foundation.
