摘要：

In order to investigate the influence of particle-size distribution on permeability of sand, the influence of uniformity coefficient, gradation coefficient, mean diameter, and void ratio on permeability coefficient was studied by constant head test. The significance of the influencing factors was then analyzed using orthogonal experimental design, and the relationships between the factors and the permeability coefficient were discussed by control variable method. The experimental results show that the permeability coefficient increases with the increase of gradation coefficient, and decreases with the uniformity coefficient. When the uniformity coefficient increases up to a certain value, the permeability coefficient tends to be stable (e.g. Cu=11 in this study). There is a nearly linear, positive correlation between permeability coefficient and mean diameter. With the increase of the mean diameter, the increasing amplitude of permeability coefficient can be up to two orders of magnitude. © 2016, Editorial Department of Journal of Southwest Jiaotong University.
