摘要
概述了Green-Ampt模型的发展情况。由于通过Green-Ampt模型,直接计算的累积入渗量结果,与实测值相差较远,为了完善Green-Ampt两阶段模型的累积入渗量随时间变化的曲线,采用了先平移后衔接的方法。通过实验模拟,经该方法修正的计算值与实测值吻合较好。证明该方法能有效地改善Green-Ampt两阶段模型的模拟值,使其更符合实际情况。应用该方法能更准确地计算出累积入渗量随时间的变化过程,对完善Green-Ampt模型,扩展其应用范围有重要意义。
The development of Green-Ampt model has been summarized in this paper. Because the result of the cumulative infiltration using the model has great error, the authors used the translation and link method to improve the cumulative infiltration curve which varies with time. The modification makes the simulation close to the experimental data. It consequently indicates that this method can improve the simulation of the two-stage Green-Ampt model, and make it more suited to the practical condition and can be used in wide areas.
