【摘要】 通过对不同饱和度、干密度下非饱和土的渗透性研究,可以看出,在饱和度较低时,湿度对渗水性的影响大于对渗气性的影响,在饱和度较高时,湿度对渗气性的影响大于对渗水性的影响;在低饱和度范围内,干密度对渗透性影响均较小,在高饱和度范围内,干密度对渗气性影响较大。更多还原

【Abstract】 In the paper, the permeability of unsaturated soils having different moisture and density is investigated. Results got from experimentshow that moisture has more significant influence on water permeability than on air permeability in the low saturation case, but it is contrary inthe high saturation case. Test results also show that influence of dry density on permeability is not obvious in the low saturation, but influenceof dry density on air permeability is notable in the high saturation case.更多还原
