By means of indoor uniaxial and triaxial creep tests under different pressure of Q₂ loess with different water contents in Xi’an areas, the uniaxial and triaxial creep curves and stress -strain isochronous curves are got. The results show that Q₂ loess has nonlinearity rheological properties. On the basis of these, viscoelastic creep phase is simulated by the generalized Kelvin model, linear viscoplastic creep phase is simulated by the Maxwell model which is parallel connected by a slider, and nonlinear viscoplastic creep phase is reflected by couple of damage and plastic strain.
