To study creep characteristics of deep rock masses under low-frequency earthquakes and other loads, sandstone and marble samples were used to characterize soft rock and hard rock, respectively. Shear creep tests of anchored rock masses under fatigue loading were carried out by using the graded loading method. A new nonlinear rheological model was constructed to characterize mechanical properties of anchored rock masses under fatigue loading. Creep fatigue curves of soft rock and hard rock have clear creep characteristics including instantaneous, attenuation, steady-state and accelerated creep stages. This work provides new insights into the stability of rock masses.
