摘 要: 通过对甘肃陇西地区的湿陷性黄土做现场浸水试验和室内渗透试验、粒度分析试验,得到了陇西黄土的渗透系数(K20)随孔隙比(e)和吸力(S)的变化规律,为研究黄土浸水入渗规律,求解湿陷性黄土非稳态渗流方程做了必要的准备。 Coefficient of permeability of typical loess is obtained based on a large pooling permeation test of the loess in Gansu Province and a series of indoor tests. Changes in coefficient of permeability vs void ratio and suction of the loess are examined. It is necessary to solve the transient equation of water transport and determine the permeability of the loess.
