Abstract: To describe the creep characteristics of rocks under hydration freeze-thaw coupling conditions, uniaxial compression creep and nuclear magnetic resonance tests were conducted on marble under acidic, alkaline, neutral solutions and different freeze-thaw cycle conditions. T2 spectrum distribution and creep test results were analyzed, and coupled damage evolution was carried out. Finally, a new creep damage constitutive model considering the coupling of hydration freeze-thaw and stress w... More
