摘　　要：超长混凝土结构裂缝控制是一项系统工程,涉及材料、结构设计和施工控制三个层次。采用试验研究、现场实测和数值模拟相结合的方法,系统研究超长混凝土结构裂缝控制中的关键技术,并将研究成果应用到上海烟草集团浦东科技创新园建设项目中,取得了良好的裂缝控制效果,可为同类工程应用提供参考和依据。Crack control of super-long concrete structures is a systematic program that involves three aspects,such as materials,structural design and construction control. The methods of experimental study,field measurement and numerical analysis were adopted to study the key technologies on the crack control for super-long concrete structures. Furthermore,the research results have been applied to a super-long concrete structure located in Pudong Innovation Park of Shanghai Tobacco Group,and achieved good crack control effects. It can provide a reference for design and construction of similar structures.
