摘　　要：广交会大厦工程建筑总高度177.3m,采用钢框架-钢筋混凝土筒体结构,为减小混凝土的收缩徐变、温差、风荷载不利因素在结构施工过程中产生的不利影响,对施工过程中结构在上述荷载作用下的变形进行分析计算,并在施工中采用相应的预控、纠偏措施,确保结构施工精度。The CIEF building,177.3m high,is with steel frame-reinforced concrete tube structure. In order to reduce the adverse influ- ence on the structure during construction process,which are caused by concrete shrinkage and creep,difference in temperature and wind load. During construction process,structure deformation is analyzed and calculated,and the pre-control and corrective measures are used to ensure the accuracy of structure construction.

关 键 词：钢框架-筒体结构 变形分析 预控措施
