Abstract
In order to examine the influence of void ratio and stress-path to the Soil-Water Characteristic Curve (SWCC) of unsaturated sandy soil, suction loading and unloading tests on the specimen with different stress-path and void ratio were implemented. As results, following facts can be made clear. Hysteresis of SWCC for initially dry specimen during suction-unloading and loading can be negligible. SWCC, the relationship between void ratio and suction, and the relationship between void ratio and the degree of saturation during suction-unloading, are not influenced by the stress-path of the specimen. Void ratio seems to give no influence to the slope of SWCC, while the minimum volumetric water content of SWCC seems to be constant.
