压实黄土土水特征曲线及孔隙结构分析

Analysis of Pore Structure and Soil-Water Characteristic Curve for Compacted Loess

采用Ku非饱和导水率测量系统和扫描电镜照片,实测并分析压实黄土土水特征曲线特征,试验结果表明:黄土干密度与土水特征曲线具有密切相关性,并讨论了干密度影响土水特征曲线的微观机理。

The soil-water characteristic curve is measured and analyzed based on results of unsaturated hydraulic con-ductivity from the Ku measurement system and photographs from the scanning electron microscope .Results indicate a close relationship between the loess dry density and the soil-water characteristic curve .The microscopic influence mech-anism of the dry density on soil-water characteristic curve is also discussed .
