摘要
为了探究粒径大小对土壤水分运移的影响,用压力膜仪法测定了两种不同粒径石英砂的土壤水分特征曲线,并采用Van-Genuchten模型拟合得到土壤水分运动参数,拟合效果较好。结果表明在相同的环境条件下,细石英砂比粗石英砂具有更大的持水能力。
In order to explore the impact of particle size on the soil movement, throught determination of soil water characteristic of two different particle size quartz by pressure plate test, simulation of soil parameters is also conducted with Van-Genuchten mode. Good agreement is found between the fitted value and the experimental value. It is indicated that the water-holding capability of fine quartz is higher than of the coarse quartz in the same environment condition.
