摘　　要：西藏会展中心工程地处高海拔、低含氧量的拉萨地区,由于屋盖空间形状复杂,高度、跨度大及杆件数量较多,采用常规的安装方法都不理想。通过比选,提出了屋盖外围部分采用组合单元吊装,屋盖内部部分采用整体提升技术。此方法有效地降低了高空作业量,提高了施工效率,工程实践证明提出的施工技术具有充分的安全性和明显的经济性。Tibet Convention and Exhibition Center project, due to its location of high altitude, low oxygenlevels in the Lhasa area, and the complexity of roof shape, height, large span and lots of pipes, isdifficult for the conventional construction methods. Through comparison, a construction plan of the outerpart of the roof lifting by combining unit, the internal part of roof by integral lifting technology isestablished. This method reduces the high operation effectively, improves the efficiency of theconstruction, the finally construction result shows that the proposed construction technology is withsufficient safety and obvious advantage in economy.
