| 摘 要： | 三峡右岸三期工程施工中,为了有效控制坝体大体积混凝土内部温升,采取了高温季节使用预冷混凝土浇筑、控制混凝土出机口温度及浇筑温度、对混凝土内部人工通水进行初冷、中冷和后冷等措施。三峡三期工程大坝混凝土内部温度没有出现超标现象,混凝土温控工作取得了良好的效果。

| Abstract: | In the construction of the third stage works of Three Gorges Project,in order to effectively control internal temperature rise of mass concrete,measures are taken to pre-cool concrete placement,control mixer outlet temperature and placing temperature,as well as pre-cool,mid-cool and post cool internal concrete manually by running water in high temperature season.The internal temperature of dam concrete has not exceeded stipulated scope,and concrete temperature control has achieved good effect. |
