The soil-water characteristic curve (SWCC) is the basis for describing seepage, strength, and constitutive model of unsaturated soil.
The existing SWCC models do not work accurately for evaluating loess, because they do not consider the pore deformation that is induced by wetting.
The present study develops a new SWCC model for unsaturated loess.
The model considers the effect of wetting-induced pore deformation (WIPD) on the SWCC.
The new model includes 6 parameters, which could be confirmed by laboratory tests.
The pore volume function (PVF) was described by the WIPD.
The shift factor ξ1i and the compression factor ξ2i were introduced into the model.
The relationship between the void ratio e and ξ1i and ξ2i was established using the average pore radius.
The new SWCC model for saturated loess was improved based on the classical van Genuchten (V-G) model.
If the WIPD had not been considered, the new model would regress into the classical V-G model.
SWCC tests of unsaturated loess with different void ratios were carried out to verify the new model.
The model parameters were calibrated in the original state, and the SWCCs of different void ratios were predicted by the new model and found to be in good agreement with the test results.
