To study the creep properties of the sliding zone soils, the triaxial creep tests under different confining pressures and stress levels were performed. The confining pressures ranged from 100 kPa to 400 kPa, and the stress levels ranged from 0.30 to 0.75 for each confining pressure. Results indicated that the sliding zone soils exists obvious creep behavior. The axial strain increases with time, and the axial strain growth rate gradually decreases with time and eventually tends to a stable value. The creep process can divide into the instantaneous deformation phase, decay creep phase and steady creep phase. An empirical creep model was presented to describe the stress-strain-time of the sliding zone soils. The model calculation results have a good relationship with the test data. The empirical creep model can describe the creep rule of the sliding zone soils.
