国家体育场主桁架施工测量

摘要

The construction of large steel structure is the key point of the whole National Stadium "Bird's Nest" project,while the construction of main truss is the core of the whole steel structure construction.As the connection of main trusses tends to be carried out overhead,the positioning survey work will be quite difficult.It introduces the construction survey work of main truss which can be covered in the similior constructions..%国家体育场“鸟巢”大型钢结构的施工是整个工程的关键,主桁架的施工又是整个钢结构施工的核心.主桁架对接点均为高空对接,定位测量相当困难,文中对主桁架的施工测量工作进行介绍,提出施工中应注意的事项,对同类工程具有借鉴意义.
