Abstract

To study the creep characteristics of sandstone after thermal shock, the sandstone specimens were subjected to thermal shock treatment, and the uniaxial creep test was carried out on the treated specimens, the change rule of the creep characteristics of sandstone with the thermal shock temperature was analyzed, and the mathematical relationship between the steady state creep rate and the thermal shock temperature was established. The results show that: the onset temperature of thermal shock damage to sandstone is between 300 and 400 degrees Celsius, the degree of sandstone damage with the thermal shock temperature is nonlinear growth, macroscopic manifestation of uniaxial compressive strength reduction, creep deformation and creep rate increase; the effect of thermal shock on the creep strain of sandstone is mainly concentrated in the steady state creep stage, and the influence range is mainly concentrated between 400 and 700 degrees Celsius; the fitting function can better describe the relationship between the steady state creep rate of sandstone and the thermal shock temperature. The research results are of great significance for long-term deformation law prediction of sandstone after thermal shock.
