Triaxial load test study on the perturbation effect of rock rheology

To study the law of rheological deformation of surrounding rock caused by disturbance load under three stress state, the law of rheological deformation under different stress states was investigated in a red sandstone triaxial load test on the perturbation effect of rock rheology using a rock rheological perturbation effect triaxial test system.The results show that with the confining pressure increasing, the rheological deformations at all levels decrease, the long-term strength increase, the deformation of the rheological deformation lag behind, and the deformation damage increases.After entering the disturbance sensitive area, the rheological deformation rate increases and the deformation cannot be restored.According to the experimental results, the constitutive equations between cumulative disturbance and cumulative disturbance energy under different stress states are obtained.
