The Helankou petroglyphs offer precious data for understanding the lifeways of ancient pastoralists. However, in Helankou, combination unique climate conditions and complex hydrochemical environments has accelerated weathering sandstone-petroglyph carriers, leading to numerous at risk vanishing. In response, this study employed freeze-thaw wet-dry cycle experiments simulate actual environmental sandstone. Subsequently, sandstone that underwent was subjected further testing analysis. goal comprehensively understand performance change patterns micro-mechanisms under stress, thus providing scientific theoretical support petroglyph conservation. results indicate effects wet-dry, degradation processes can be attributed a diverse mechanisms such as swelling-shrinkage, hydrolysis, frost heave, dissolution, salt crystallization, which alter physical parameters, particle size distribution, mineral composition, structural integrity
