Abstract:Because the effect of humidity is related to the scope and time of humidity diffusion, the degradation of mechanical properties and the deformation in surrounding rocks caused by humidity diffusion varies with space and time, which is considered as the source of rheological behaviors of rock. Therefore, by introducing the relationship between the increase of humidity and degradation of rock mechanical properties, we propose the humidity-stress-damage coupling based rheological model. The simulations on creep and relaxation behavior of rock reconstructed the mechanism of rhelogical behavior of rock under humid condition. By the comparative analysis of the difference between the proposed rhelogical model and the conventional rheological model of rock, the source of rheological behavior of rock is further elaborated.
