摘　　要：针对厦门财富中心钢管混凝土的施工特点,配制出满足工程要求的C60钢管自密实混凝土,并对钢管自密实混凝土的生产及施工进行研究。通过验证表明,经过优化设计的C60钢管自密实混凝土能够满足工程施工要求;在生产中采取降低混凝土拌合物水化热的措施,并在施工中采取合理的技术措施,能够保证自密实混凝土在钢管中的填充质量,避免大体积混凝土的裂缝产生。The C60 self-compacting concrete filled steel tube was prepared and its production and construction were also researched in order to meet the construction features of concrete filled steel tube in Xiamen Fortune Center project.The result shows that C60 self-compacting concrete filled steel tube can meet the construction requirement by optimizing design.The self-compacting concrete can be filled better in the steel tube by using correct technology,and the cracks of mass concrete can be controlled through reducing the hydration heat of the concrete.
