As　large-scale　photovoltaic　power　plants　gradually　move　towards　high-altitude　and　cold　regions,　accurate　evaluation　of　the　impact　of　freeze-thaw　erosion　hazards　on　the　safe　operation　of　photovoltaic　power　plants　is　essential.　This　study,　based　on　a　large-scale　photovoltaic　power　plant　in　a　high-altitude　and　cold　area,　conducted　an　initial　calculation　of　the　freeze-thaw　erosion　intensity　in　the　study　area　by　selecting　appropriate　environmental　factors.　By　coupling　human　engineering　quantitative　indicators,　a　targeted　and　reasonable　evaluation　model　for　the　freeze-thaw　erosion　intensity　of　photovoltaic　sites　was　proposed,　and　the　freeze-thaw　erosion　intensity　and　its　spatial　distribution　under　multiple　environmental　factors　and　human　engineering　conditions　were　explored.　The　results　showed　that　the　freeze-thaw　erosion　intensity　of　the　photovoltaic　site　was　generally　moderate,　with　a　certain　degree　of　concentration　and　spatial　heterogeneity　in　its　distribution,　which　was　mainly　affected　by　topography,　climate,　and　vegetation　factors.　Furthermore,　the　construction　of　the　photovoltaic　power　plant　had　a　certain　weakening　effect　on　the　freeze-thaw　erosion　intensity　of　the　site.　The　research　results　can　provide　reference　and　guidance　for　the　freeze-thaw　erosion　evaluation　of　similar　large-scale　projects.　©　2024　Institute　of　Engineering　Mechanics　(IEM).　All　rights　reserved.
