Abstract: Considering the external influences on rock deformation as instantaneous elastic damage defined with the reduction of instantaneous elastic modulus and long-term creep damage defined with the reduction of long-term creep modulus, kBurgers model with damage is presented. In addition, three-dimensional model considering the Poisson’s ratio and bulk modulus as the constant is established separately; and the transformational relations between the parameters are obtained. According to a case study, the damage evolution of model parameters considering water content changing under the assumption of constant bulk modulus is studied. The damage evolution equations of instantaneous elasticity and long-term creep under the assumption of constant bulk modulus are obtained, which prove that transformational relations between model parameters are reasonable.

Key words: viscoelasticity, constant bulk modulus, constant Poisson’s ratio, damage
