摘　　要：昆明春之眼商业中心项目关键结构均采用钢–混凝土组合结构,其多腔体多边形钢管巨柱中,钢和混凝土的良好粘结至关重要。巨柱采用C65自密实混凝土,考虑到高强混凝土早期自收缩较大,混凝土水化放热增快、温升增高,因此,对多腔体多边形钢管巨柱混凝土浇筑质量、钢材粘结质量展开专项研究,并得出相关结论。Key structures of Kunming Eye of Spring Commercial Center project are of steelconcrete composite structure and reliable cohesion between steel and concrete are very important for multi-chamber polygonal steel pipe huge column.The huge column was made of C65 self-compacting concrete.Considering the high shrinkage of high-strength concrete at early curing age,hydration heat acceleration and temperature increase,this paper carried out special study on the concrete casting quality and steel cohesion quality of multi-chamber polygonal teel pipe huge column and got relevant conclusion.
