"Bird's nest" in the huge steel mesh Wai, covered with 9.1 million people in the stadium; sightseeing staircase naturally become an extension of the column disappeared, even force such as branches like no clear point, let a person feel every seat is equal, place oneself among them as back into the forest; the Sunlight filters into diffuse shaped inflatable membrane, made the stadium bid farewell to the sun shadow; the topographic uplift 4 meters. Inside the ancillary facilities, to avoid excavation the consumption of huge investment.“鸟巢”以巨大的钢网围合、覆盖着9.1万人的体育场；观光楼梯自然地成为结构的延伸；立柱消失了，均匀受力的网如树枝般没有明确的指向，让人感到每一个座位都是平等的，置身其中如同回到森林；把阳光滤成漫射状的充气膜，使体育场告别了日照阴影；整个地形隆起4米，内部作附属设施，避免了下挖土方所耗的巨大投资。The bird's nest is a large span curve structure, a large curved box structure, design and installation are very challenging, in the process of construction everywhere cannot do without the support of science and technology. The "bird's nest" with today's advanced construction technology, the whole project has twenty or thirty technical problems, the steel structure is the one and only the world. The "bird's nest" steel structure weighing 4.2 million tons, maximum span of 343 meters, and the structure is quite complex, the three dimensional twisted like fried dough twist processing, in after the construction of the settlement, deformation, loading and other problems are gradually resolved, related problems in construction technique is also listed as a key project of Ministry of science and technology.鸟巢是一个大跨度的曲线结构，有大量的曲线箱形结构，设计和安装均有很大挑战性，在施工过程中处处离不开科技支持。“鸟巢”采用了当今先进的建筑科技，全部工程共有二三十项技术难题，其中，钢结构是世界上独一无二的。“鸟巢”钢结构总重4.2万吨，最大跨度343米，而且结构相当复杂，其三维扭曲像麻花一样的加工，在建造后的沉降、变形、吊装等问题正在逐步解决，相关施工技术难题还被列为科技部重点攻关项目。
