| Abstract: | The massive concrete construction is a special technique in civil engineering at present.In the light of characteristics of massive concrete of pile cap of Bridge over Yangtse River at Tianxingzhou in Wuhan City,the measures for cracks control in massive concrete were proposed.Detailed thermal calculations were carried out according to the criterions.The calculation results showed that the maximum temperature difference inside and outside the concrete after pouring doesn＇t exceed 25.Practice proved that effect of crack control by the measures is obvious,which provides good reference to design and construction of similar massive concrete. |
