本文利用已有的土壤水分运动参数标定成果,用数值方法求解了标定的土壤水分运动基本方程,得出了某一初始含水率分布条件下、薄层积水时土壤水分运动入渗的标定解.作为示例,给出了不同标定因子地点处的土壤水分入渗过程.本文还介绍了Philip入渗公式的标定方法,结合在河南、山东二省所进行的三组入渗试验资料,对入渗标定因子的确定、入渗量的标定及入渗量的空间分布等问题进行了初步计算和分析.
In this paper, the existing results of soil moisture movement parameters were calibrated, and the basic equation of soil water movement was solved numerically. The calibration of soil water movement infiltration under a certain initial water cut distribution was obtained. As an example, the process of infiltration of soil water at different calibration factors is presented.This paper also introduced the calibration method of Philip infiltration formula, combined with three groups of infiltration test data in Henan and Shandong provinces, Infiltration factor to determine the infiltration of the calibration and infiltration of the spatial distribution of issues such as the initial calculation and analysis.
