摘要
建立了一种与R ichards方程等价的新形式的土壤水分运动模型,讨论了新形式土壤水分运动方程在建立特征有限元数值模型中的简便性,并利用实验数据进行了数值模拟。结果表明,此模型精度高,符合实际工作要求。
A new model of water flow in soils which is equal to Richards equation is set. The simplicity of the new model of water flow in soils in setting the characteristic finite element numercal model is discussed. And the numerical simulation is performed by lab data. The result demonstrates that the modcl meets the demand of practical work because of its higher precision.
