摘　　要：国外某机场新航站楼屋面主承重构件由双向弯曲的大跨度空间三角拱桁架组成,构件异形、倾斜、重量较大,吊装施工难度极大.以空间三角拱桁架为例,在海外工程不断探索实践,适应当地不同规范要求,从吊装设备选用、寻找重心、受力计算、过程分析等方面介绍了吊装施工技术,探索出了一条安全、高效、快捷、精细化的吊装专业化管控道路.In the new terminal building of an oversea international airport,main support components,including dual-bending long span spatial triangular arches are complex and heavy.It is highly difficult to lift the members.Based on the BS standard and local laws,this paper discusses the method of lifting heavy steel structural segment from overseas by choosing crane,finding the center of gravity,internal force calculation,lifting procedure analysis and so on.The rigging plan procedure is very safe,efficient,fast,elaborate and suitable for all the similar heavy liftings.

关 键 词：大跨度结构 空间三角拱桁架 吊装技术
