摘　　要：针对核岛内部结构墙体钢筋密集、预埋件多、洞口多、施工难度大、混凝土抗裂性能和表观质量要求高等特点,进行核电自密实混凝土性能及工程实例研究。分析了核电自密实混凝土工作性能、机械性能、耐久性与各影响因素的关系,研究成果可为核岛主体工程大范围应用自密实混凝土提供依据。According to the characteristics of nuclear internal structure, such as dense steel bar distribution, more embedded parts and openings, construction difficulty, highrequest to crack resistance and apparent quality of concrete,the performance of self-compacting con- crete and project example is studied.The relationships of influencing factors and self-compacting concrete performances are analyzed.These results could provide a basis for applying self-compacting concrete in nuclear plant construction.

关 键 词：自密实混凝土 内部结构 混凝土性能
