摘　　要：介绍了某工程基础大体积混凝土分段、分层施工方法。采用间歇分层浇筑 ,使一部分水化热在混凝土呈塑性状态下释放 ,大大降低了水化热对混凝土凝结硬化的影响。在浇筑时 ,再辅以混凝土缓凝技术 ,能有效地散发水化热 ,降低混凝土早期温度 。the segmentation,layered construction method and construction sequence of a mass concrete construction for one project foundation is introduced.The interrupted layered pouring is adopted to make some heat of hydration released when the concrete in plastic stage and reduce influence of the heat of hydration on the condensation and harden of concrete.In pouring the slow setting technology is adopted to make the effective release of hydration heat to reduce the temperature of concrete in early stage.

关 键 词：基础 大体积混凝土 分层浇筑 温差 施工方法
