Based on the data from ordinary triaxial test of Yan’an Q₂ loess under different confining pressures and misture contents, this paper establishes the constitutive model of triaxial statistical damage for Yan’an Q₂ loess by introducing rock statistical damage theory in the damage constitutive model of Yan’an Q₂ loess. In the meantime, the paper considers the effect of damage threshold on Yan’an Q₂ loess damage variable as well.  The paper indicates that with the consideration of damage threshold, loess statistical damage constutive model can better reflect the characteristics geotechnical engineering design in the loess plateau ration of damage threshold, loess statistical damage Yan’an Q₂ loess deformation and failure, with a reference for geotechnical engineering design in the loess plateau.
