Abstract: The study of the degradation mechanism of freeze-thaw damaged rock holds significant theoretical importance in understanding freeze-thaw disasters, predicting disasters, and designing tunnel protection systems in cold regions. Based on the volume expansion theory, this research establishes a correlation between irreversible volume increase and the number of freeze-thaw cycles, and also deduces the law of radial heat transfer for cylindrical samples during freeze-thaw cycles. Considering the free... More
