| Abstract: | In a high-cold zone,the yearly variation of temperature is great.As the temperature drops down,horizontal and vertical cracks appear in the breast-wall of a deep-water sluice under strong restriction by gate piers and action of various loads,and threaten the durability of structures and materials.Measures are worked out to treat concrete cracks at alternation of high-cold and severe hot weather conditions. |

| Keywords: | great temperature difference strong restriction seepage control crack |
