The hierarchical loading compression creep test fails to fully consider the viscoplastic strain in the stable creep, so the cyclic loading compression creep test is adopted to realize the separation of viscoelastic and viscoplastic strain, so that the viscoelastic and viscoplastic strain can be fully considered in each stage of the creep. Takes the diorite porphyry of Jurong Hydropower Station as an example to discuss the creep characteristics of this type of rock. Before failure, the instantaneous elastic strain, viscoelastic strain, and instantaneous plastic strain increased linearly with the deviator stress gradually increasing, and with the increase of the deviator stress, growth rate of viscoplastic strain got bigger and bigger. Introduce the fractional Abel viscous pot and Kelvin model to form a new viscoelastic model; use it to replace the linear Newtonean fluid in the traditional viscoplastic model and establish a viscoplastic damage model based on damage variables. Then the new viscoelastic plastic model and viscoplastic damage model are connected in series with the transient elastic model and the transient plastic model to form a new rock creep damage model. Finally, the model is fitted with the rock creep curve to prove the applicability of the model.
