| 摘 要： | 从分析下渗水受力状态出发，根据土壤水动力学和流体力学，推导了不同情况下下渗流速和下渗强度的计算公式；论证了一般情况下下渗水有重力流和毛细管流两种流态，下渗流流速与下渗强度取决于渗透系数、粒度和球度等土壤物性，并受土壤原含水量及潜水面埋深的制约

| 关 键 词： | 下渗流流速，下渗强度，渗透系数，潜水面 |

| Abstract: | The formulas of the speeds and intensity of infiltration on varied conditions are derived based on the theory of soit hydraulics and hydromechanics. Gravitational current and capillary current of infiltratin water on common condition are discussed. Infiltration speed and intensity are dominated by soil physic characteristics such as permeability, granularity and spherical degree, while restricted by soil water content and depth of water table. |

| Keywords: | \ infiltration current speed infiltration intensity coefficient of permeability water table |
