[摘要] 国家体育馆是2008年奥运会主要场馆之一，钢屋盖采用双向张弦结构形式，是目前世界上跨度最大的双向张弦结构。国家体育馆钢屋盖的特点是设计和施工都具有极高的创新性，本文对钢屋盖建造过程进行了比较详细的描述，旨在提出一种类似创新性工程的解决方案：即在确定方案阶段就利用科学研究的方法对设计技术和施工技术进行详尽的研究，把设计和施工过程中可能出现的问题解决在方案阶段。国家体育馆实践证明采用设计、施工、科研一体化的思路对此类高难度工程有借鉴意义。

Abstract: The National Indoor Stadium is one of the most important stadiums for 2008 0lympic Games. The structure type of the stadium roof (114mx144. 5m)  is Two-way Beam String Structure( TBSS),a new and efficient spatial structure. The design and construction of The National Indoor Stadium are full of challenge, so a mode called "Design & Construction & Research" is applied. This mode can be explained briefly as follow: Solve the problems of the design and construction technology by the research method during the structural type decision period. This mode may benefit the similar high-difficulty projects.
Keywords: two-way beam string structure; design&construction&research
