摘　　要：国家会议中心工程地下一层展览区部分顶板为单向密肋板,肋高700mm,宽1500mm,肋间距为1500mm,密肋楼板上表面设计有复杂繁多的设备管沟。同时这部分在功能划分上为展览厅,空间巨大,人流密集,并且需要满足车辆驶入的要求,设计荷载为35kN/m2。对此在模板、钢筋、混凝土施工中采取了专项措施。In some part of the underground exhibition area of the National Conference Center Project at Beijing Olympic Park （Area B）, the ceiling floor is arranged dense ribs in one direction with rib height of 700mm, width 1500mm and rib space 1500mm, and a lot of complicated equipment ducts are arranged on the＇ floor surface. Meanwhile, as an exhibition hall, it not only has a big space and dense person flow but also needs to meet the requirement of vehicle driving with design load of 35 kN/m^2.
