台山核电厂HRA反应堆厂房筏基大体积混凝土浇筑温控措施

Temperature control measure used in HRA reactor building of taishan NPP

台山核电厂为我国首次引进的欧洲第三代先进压水反应堆堆型(EPR),为世界建造的第三座该型核电站,其反应堆厂房筏基混凝土工程量约9 300 m3,一次浇筑完成。通过合理配制混凝土,实施合理的施工方案,采取合理的养护措施,全面掌控混凝土的温度发展,保证反应堆厂房筏基不产生有害裂缝。

The Taishan NPP is the first reactor style（EPR） builded in China,and is the third one all of the world.The concrete quantity of the reactor building raft is 9 300 m3,concreting for one layer.By the way of designing concrete formula suitably,writing suitable construction project,adopt suitable curing measure,totally control the temperature,to ensure the raft have no crack.
