ABSTRACT: Creep is usually associated with soft rock. Hard rock can also exhibit such behavior when the mine depth is large. A model is necessary to describe the creep behavior of rocks. In this paper, the Burgers creep model is used to describe the creep behavior of a rock under different stress conditions. Its ability of describing and predicting the time-dependent responses of rock was tested against experimental results available in the literature. The model parameters were obtained through the application of curve fitting technique on experimental results obtained under one confining pressure at one deviatoric stress level. The predictability of the calibrated model was tested against the experimental results under the same confining pressure, but at different deviatoric stress levels. The good agreements between the Burgers creep models and the experimental results indicate that the Burgers creep models are able to describe and predict the creep behavior of rocks under different stress states.
