Failure mechanisms and paths of freeze–thaw-treated single-flaw sandstone under triaxial compression in ultra-high-altitude cold-region open-pit mine slopes

Abstract Ultra-high-altitude cold-region open-pit mine slopes are affected by seasonal freeze-thaw (F-T) weathering, structural discontinuities, and excavation-induced stress changes. Sandstone sampled from a mining bench at 5074 m a.s.l. in the Dahongliutan area of Hotan County,...
