This research aims to explore the creep damage dynamics of white sandstone influenced by short-term freeze-thaw cycles.
Conducted multi-gradient freeze-thaw cycle tests on white sandstone.
Performed graded loading creep acoustic emission tests.
Developed a creep damage constitutive model using a seven-element viscoelastic model.
Mass loss rate and P-wave velocity reduction correlate positively with freeze-thaw cycles.
Instantaneous axial strain increases with stress levels across different cycles.
Cumulative acoustic emission event rates significantly decline with more freeze-thaw cycles.
