Abstract
In order to accurately simulate the creep behavior of rocks under the action of complex environments, the damage creep model considering the environmental effects (hydrous conditions and freeze–thaw cycles) is investigated. Through the statistical analysis of the test results of rocks under different water contents and freeze–thaw cycles, it is believed that the rock damage includes time-independent initial damage and time-dependent subsequent damage. Then, the mathematical expression of the creep failure time of rocks is calibrated with the help of the environmental effect of the characteristic stress, and a subsequent damage factor that can describe the damage creep of rocks under the environment-mechanics interaction is given, and its numerical analysis is carried out. Ultimately, a unified fractional rheological mechanical model is established by combining the extended fractional viscoplastic theory, Drucker-Prager yield theory considering damage effect and modified effective stress. The universality of the new model is verified by the damage creep test results of rocks under different environmental loads. The result indicative of the unified fractional rheological mechanical model can accurately describe the nonlinear creep behavior of rock under complex environment, and the model simplifies the loading conditions and viscoplastic theory of the traditional unified rheological mechanical model.
