摘　　要：北京绿地中心工程属超高层工程,其钢筋桁架楼承板混凝土顶板面积达7万m2。在楼承板施工中进行了顶板混凝土裂缝研究,并通过对楼承板拼缝工艺、标高控制、支撑方式和集中荷载等方面采取了有效措施,较好地控制了钢筋桁架楼承板混凝土裂缝的产生。In the super-high Beijing Greenland Center project, the top concrete slab of steel-bar truss deck covered an area of 70000m2. Concrete crack on top slab was researched during construction of floor deck and effective measures were adopted for connection among floor decks, elevation control, support mode and concentrated load, etc., so as to effectively prevent generation of concrete crack on steel-bar truss deck.
