| 摘 要： | 从非饱和土土水特征曲线方程出发，根据渗透函数和土水特征曲线的关系，推导出了非饱和土渗透函数方程。用拟合土水特征曲线试验结果所得参数形成的渗透函数方程与测量结果一致，由于土水特征曲线方程和渗透函数方程含有相同参数，说明了两个方程之间有内在联系。

| Abstract: | Based on the equation of soil water feature curve and the relationship between soil water feature curve and permeability function, the permeability function equation of unsaturated soil is derived. The permeability function equation formed with the parameters obtained from fitting the experimental results of soil water characteristic curve is found to be in coincidence with the actual measured results. Since soil water characteristic curve equation and permeability function have the same parameters, there is an internal connection between the two equations. |
