[摘要] 國家體育館是2008年奧運(yùn)會主要場館之一，鋼屋蓋采用雙向張弦結(jié)構(gòu)形式，是目前世界上跨度最大的雙向張弦結(jié)構(gòu)。國家體育館鋼屋蓋的特點(diǎn)是設(shè)計(jì)和施工都具有極高的創(chuàng)新性，本文對鋼屋蓋建造過程進(jìn)行了比較詳細(xì)的描述，旨在提出一種類似創(chuàng)新性工程的解決方案：即在確定方案階段就利用科學(xué)研究的方法對設(shè)計(jì)技術(shù)和施工技術(shù)進(jìn)行詳盡的研究，把設(shè)計(jì)和施工過程中可能出現(xiàn)的問題解決在方案階段。國家體育館實(shí)踐證明采用設(shè)計(jì)、施工、科研一體化的思路對此類高難度工程有借鑒意義。

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
