In order to describe the relationship between matrix suction and water content,soil-water characteristic curve(SWCC) tests in lab and field were carried on.
为了描述非饱和土基质吸力与含水量的关系特性,进行了室内外土体水分特征曲线(SWCC)测试,分析了试样物质成分、塑性指数、孔隙结构、应力状态等因素对SWCC测试的影响;在自然边坡、挖方边坡、填方边坡上进行了基质吸力变化规律的实测,对比了在不同应力、填土条件下基质吸力变化规律的差异性。

Based on the observation data of soil negative pressure h and soil water content θ obtained at the Luancheng Agricultural Ecosystem Station of Chinese Academy of Sciences,soil-water characteristic curve(h-θ carve)are described by using the van Genuchten model(VG model).
根据中国科学院栾城试验站大田土壤剖面所采土样实测土壤负压h和土壤含水率θ实验数据,采用van Genuchten模型来描述土壤水分特征曲线(h-θ曲线),VG模型中的参数利用Matlab非线性拟合函数来确定,通过对四参数模型和三参数模型的比较表明,四参数模型拟合的参数与三参数模型中的参数非常接近,但四参数模型能够更好地拟合实测数据,误差比三参数模型相对较小。
