The rock creep model is an important part of the study of the time-dependent me­chanical behavior of rock. To ensure the safe excavation and long-term stable operation of deep engineering, a creep damage factor considering accelerating creep initiation time and creep failure time was proposed. By introducing the initial damage of excavation disturbances at different depths, a creep damage constitutive model for rocks at different depths considering disturbances was derived. This creep model has fewer parameters that are easy to obtain. It can better describe the accelerating creep characteristics of rock at different depths, especially for a more accurate description of the long-term creep mechanical behavior of deep rock.
