Abstract
通过室内试验方法利用Philip和Green-Ampt入渗模型对3种土壤水平一维入渗进行了分析,对Green-Ampt入渗模型的含水率分布进行了修正从而改进二模型参数的互推公式,根据互推参数分别计算累积入渗量,并与实测值进行比较。结果表明,修正模型能很好地反应土壤入渗性能,随着土壤粘性的增加,Philip模型参数吸湿率S和Green-Ampt模型参数kssf都逐渐减小,用Philip模型推求修正的Green-Ampt模型参数k′ss′f具有较高的精度,且对于不同质地土壤的入渗表现出不同程度的正效应,此互推公式可应用于不同土壤水平入渗的试验研究。 更多还原The analyses of one-dimensional soil water infiltration in 3soils were studied through laboratorytesting methods used by Philip and Green-Ampt infiltration model.The moisture content of Green-Amptinfiltration model was adjusted to improve the distribution of two model parameters.According to the pusheach formula,the cumulative infiltration was calculated respectively and was compared with the measuredvalues.The results showed that the modified model can well reflect the soil infiltration properties.The absorption rate(S)of Philip model parameters and Green-Ampt model parameters(kssf)were gradually reduced with the soil viscosity increased.The accuracy of Green-Ampt model parameters(k′ss′f)were highby Philip model modified and showed different degrees of positive effect.It is confirmed that this push eachformula could be used to different levels of soil infiltration studied
