Yielding of Unsaturated Compacted Silty Soil Under Anisotropic Conditions
Considerable attempts have been made in recent years to develop a better understanding of the mechanical behavior of unsaturated soils in terms of elasto-plastic critical state constitutive models. An important feature of the models is the suggestion of the existence of a yield surface in mean net stress: deviator stress: suction space. This paper presents the results of experimental tests for investigating the shape of yield surface for compacted silty soils. A comprehensive set of laboratory experiments has been undertaken in a double-walled triaxial cell. The method of axis translation was used to create the desired suction in the samples. The results show that constant suction cross sections of the yield surface were approximately elliptical in shape, and inclined to the axes; the size of the elliptical yield curves increased with increasing suction and the flow rule was non-associated.
