     国家体育场建筑顶面呈鞍形,长轴为332.3米,短轴为296.4米,最高点高度为68.5米,最低点高度为42.8米。在保持“鸟巢”建筑风格不变的前提下,新设计方案对结构布局、构建截面形式、材料利用率等问题进行了较大幅度的调整与优化。原设计方案中的可开启屋顶被取消,屋顶开口扩大,并通过钢结构的优化大大减少了用钢量。大跨度屋盖支撑在24根桁架柱之上,柱距为37.96米。主桁架围绕屋盖中间的开口放射形布置,有22榀主桁架直通或接近直通。为了避免出现过于复杂的节点,少量主桁架在内环附近截断。钢结构大量采用由钢板焊接而成的箱形构件,交叉布置的主桁架与屋面及立面的次结构一起形成了“鸟巢”的特殊建筑造型。主看台部分采用钢筋混凝土框架一剪力墙结构体系,与大跨度钢结构完全脱开。 

     The Beijing National Stadium, also known as the bird's nest will be the main track and field stadium for the 2008 Summer Olympics and will be host to the Opening and Closing ceremonies. In 2002 Government officials engaged architects worldwide in a design competition. Pritzker Prize-winning architects Herzog & de Meuron collaborated with ArupSport and China Architecture Design & Research Group to win the competition. The stadium will seat as many as 100,000 spectators during the Olympics, but this will be reduced to 80,000 after the games. It has replaced the original intended venue of the Guangdong Olympic Stadium. The stadium is 330 metres long by 220 metres wide, and is 69.2 metres tall. The 250,000 square metre (gross floor area) stadium is to be built with 36 km of unwrapped steel, with a combined weight of 45,000 tonnes. The stadium will cost up to 3.5 billion yuan (422,873,850 USD/ 325,395,593 EUR). The ground was broken in December 2003, and construction started in March 2004, but was halted by the high construction cost in August 2004. 

     In the new design, the roof of the stadium had been omitted from the design. Experts say that this will make the stadium safer, whilst reducing construction costs. The construction of the Olympic buildings will continue once again in the beginning of 2005.


   “鸟巢”是2008年北京奥运会主体育场。由2001年普利茨克奖获得者赫尔佐格、德梅隆与中国建筑师合作完成的巨型体育场设计,形态如同孕育生命的“巢”,它更像一个摇篮,
寄托着人类对未来的希望。设计者们对这个国家体育场没有做任何多余的处理,只是坦率地把结构暴露在外,因而自然形成了建筑的外观。
