土壤质地、地下水位埋深、前期雨量以及入渗边界条件对累计入渗量 F与入渗强度 f之间的关系都有较大的影响。本文利用所建立的 h方程数学模型研究了薄层积水条件下 ,不同地下水位埋深不同降雨强度的入渗规律 ,得出以下结论 :(1 )在均匀降雨条件下 ,当产生积水以后 ,F- f 关系式与薄层积水条件下的 F- f 关系式一致 ;(2 )地下水位埋深大于 4m,F- f 关系式不随地下水位的变化而变化。 Soil texture, groundwater depth, pre-rainfall and infiltration boundary conditions have a greater impact on the relationship between cumulative infiltration F and infiltration intensity f. In this paper, the mathematical model of h-equation was established to study infiltration law of different rainfall intensity under different water table conditions under the conditions of thin-layer water accumulation. The conclusions are as follows: (1) Under the condition of uniform rainfall, , F-f relationship and F-f relationship under the conditions of thin-layer water storage; (2) The depth of groundwater table buried depth greater than 4m, F-f relationship does not change with the groundwater level changes.
