Abstract: Soil water characteristic curve plays a significant role in unsaturated soil mechanics,
geotechnical and geoenvironmental engineering. A series of soil water characteristic tests for
remoulded loess specimens under no stress state and certain consolidation stress states. For
Xi'an loess and Saskatchewan silt, Indian Head till in the past literatures, the result shows that the
evolutions of water-solid volumetric ratio with matric suction can be normalized by a single curve
in the certain consolidation or preconsolidation void ratio ranges. A new model considering void
ratio variation with stress is proposed based on van Genuchten model. In addition, the model can
not only be in good accordance with the test data, but also provide a new insight into the
hydro-mechanical constitutive relationship for unsaturated soils.
