N2 - The purpose of this contribution is that of investigating characteristics and uniqueness of instability loci for partially saturated soils. Unsaturated soils can in fact approach a less and less stable condition as a consequence of a saturation path. The increase in the degree of saturation can be induced either by the application of external loads or by wetting processes. The influence of initial saturation conditions is studied. Finally the effect of different stress paths on the location of instability boundaries is briefly discussed.
