Abstract: The direct shear tests of 16 specimens of loess (4 groups) with controlling matric suction were carried out; and the shear strength curve of the unsaturated and undisturbed loess were obtained by using a new direct shear meter for unsaturated soils. Strength characters of unsaturated and undisturbed loess were analysed and inquired. The study shows that the shear strength curves with different matric suctions have different locations in a - figure as well as linear rising; the friction angle of undisturbed loess has little change with the change of matric suction; but the cohesion has a linear increase with the increasing of matric suction.

Key words: undisturbed loess, matric suction, strength
