The effect of cooling rate and supplying water condition on the freezing properties of silty clay in seasonal freezing zones.

ABSTRACT: A unidirectional freezing experiment was performed on silty clay from the Changchun area using a custom freezing apparatus to examine temperature variations, frost deformation, and moisture migration within the soil samples. The study aimed to investigate the influence of cooling rate and water supply conditions on the soil's frost heave properties. The results indicated that under different cooling rates and water supply conditions, the internal temperature evolution of the specimens could be categorized into four distinct stages: rapid cooling, rebound and stabilization, sustained cooling, and steady state.The final temperature of specimens under open water supply conditions was 2-3°C higher than that under closed conditions. The cryostructure exhibited a reticulated pattern, and its wid
