Abstract: The mechanical characteristics of natural soils are affected by its structure significantly. The special mechanical behavior of natural soils and the influence of stress path on natural soils are disclosed through the comparison of multiple stress paths experimental results between natural soils and reconstituted soils. The characteristics of structure and incomplete consolidation of natural soils are shown in the normal consolidation experiment. The damage of the structure of the incomplete consolidation natural soils caused by the increment of volumetrical strain is more significant than that of shear strain. The influence of the structure on the strength of natural soils is mainly expressed as the increase of internal friction angle. At small strain, natural soils different from the reconstituted soils markedly, such as high stiffness, obvious nonlinearity. Through the comparison of experimental results of natural soils derived from different directions, the anisotropy of natural soils, which is more obvious as the decrease of strain, is illustrated.

Key words: natural soils, clay, structure, small strain, stress path, incomplete consolidation
