AB - 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.
