摘要：

Freeze-thaw damage is a common form of damage to concrete materials, especially in cold regions. The deterioration process of hydraulic concrete material of channel lining structure the under the freeze-thaw cycles is analyzed. The damage evolution equation is deduced and freeze-thaw zone is discussed. The results indicate that the deterioration of hydraulic concrete material under the freeze-thaw cycles occurs mostly in the region of water fluctuation district, which is the freeze-thaw zone. The load capacity of structure after freeze-thaw process is also degraded major in the freeze-thaw zone and has little effect to the other section. This means that the damage of the freezing-thawing process in the coldest region will cause the local failure. The local protection in the freeze-thaw zone region is mostly important to concrete material in cold regions.
