中文摘要 在分析降水头入渗过程的基础上,应用Green-Ampt入渗模型,并假定降水头垂直一维入渗也适用于Philip入渗模型的前提下,通过二模型参数间的转换关系建立了适用于降水头垂直一维入渗的累积入渗量的显式函数,并利用3种不同土壤进行了检验。结果表明,降水头垂直一维入渗的累积入渗量可适用于Philip入渗模型,所建立的降水头垂直一维累积入渗量显函数的整体相对误差分别为1.89%、0.02%、0.10%;均方根误差分别为0.13、0.07、0.08,模型的模拟精度较高,能有效地模拟连续降水头条件下的入渗过程。
英文摘要Abstract:Based on the analysis of precipitation head infiltration,it was on the premise of postulate for precipitation
 vertical one-dimensional infiltration also being suitable to the Philip infiltration model and applied
Green-Ampt infiltration model to study the approximate explicit solution.The proper explicit function to
cumulative precipitation vertical one-dimensional infiltration was established with the conversion relationship
 of the two models and was tested under 3different soils.The applicability of Philip infiltration model
under precipitation head vertical one-dimensional infiltration was verified.The explicit function to cumulative
 precipitation vertical one-dimensional infiltration was established based on the Green-Ampt infiltration
model,whose IRErespectively was 1.89%,0.02%,0.10% and RMSErespectively was 0.13,0.07,
0.08.The calculated value of cumulative infiltration tallied with the actual value well.It was suggest that
this function had the good precision and could simulate the process of continual precipitation head infiltration
 effectively.
