非充分供水土壤水分入渗模型的试验研究

基于均质土壤的非充分供水入渗试验数据,通过回归分析的方法,分析讨论了Kostiakov二参数模型、三参数模型、Horton模型和Philip模型,对非充分供水条件下土壤控制阶段入渗过程的适用性。结果表明:Kostiak-ov二参数模型、三参数和Philip模型的显著性和相关性都较高;综合考虑Kostiakov三参数模型的显著性、相关性以及回归参数与实际入渗过程边界值的吻合性,认为用Kostiakov三参数模型描述土壤入渗能力控制阶段入渗特性效果最好。

Experimental Study on Soil Infiltration Model in Non-sufficient Water Supplied

On the basis of the non-sufficient infiltration test of homogeneity soil,the paper discussed Kostiakov two parameter model,Kostiakov three parameter model,Horton model and Philip model,and analyzed the fitness for the infiltration process of Non-sufficient water supplied soil control stage by using the regression method.The result shows: the first is that significance and relevance of Kostiakov two parameter model,three parameter mode and Philip model is rather high;the second is that the effect of infiltra...
