摘　　要：美兰机场二期航站楼采用超长无变形缝混凝土结构,施工过程中通过采取多种措施减少了超长混凝土无变形缝结构因混凝土收缩产生的裂缝。论文介绍了施工过程中,对补偿收缩混凝土、纤维混凝土的配合比、强度、浇筑以及养护的要求,并对跳仓法、加强后浇带以及预应力温度筋的设计以及施工要点进行总结。Meilan airport terminalⅡadopts extra-long concrete structure without deformation joints.During the construction process,various measures were taken to reduce the cracks caused by concrete shrinkage in the extra-long concrete non-deformation joint structure.In this paper,the requirements for compensating shrinkage concrete,the mix ratio,strength,pouring and curing are introduced,and the design and construction points of the skip method,the reinforced post-pouring belt and the pre-stressed temperature bar are summarized.
