摘　　要：国家体育场是2008年北京奥运会的主会场。其造型呈马鞍形,外壳由钢结构编织成鸟巢状,内部为三层碗状看台混凝土结构。看台结构存在大量斜柱、斜梁、空间环梁等异形构件。钢结构总用钢量约4.2万t。施工中通过采用高强高性能混凝土技术、钻孔灌注桩后压浆技术、HRB钢筋应用技术、Q460高强钢厚板焊接技术、成套箱形弯扭构件加工制作技术等,取得了一系列研究成果,提高了我国建筑技术水平,社会经济效益和环保效益非常显著。其中7项科技成果填补国内空白,达到国际先进或国际领先水平,完成了国家级工法4项。本工程已获得结构"长城杯"金杯和中国钢结构金奖。As the main stadium for 2008 Olympic Games, National Stadium has a saddle-like configuration and a bird nest steel shell while its internal structure is three floors of bowl concrete stands in which a lot of oblique posts and beams as well as spacial ring beams are arranged, with total steel consumption of 42,000 t. Some technologies were applied in the construction, including concrete of high strength and high performance, post pressure grouting into driven cast-in-place pile, applied technology for HRB steel bar, thick plate weld of high strength steel Q460 and fabrication of bending-twisting box components and etc. The research achievements made in the project have improved the construction level of our country, reached remarkable social, economical and environmental benefits. Among them, 7 scientific achievements attain the international advanced or leading level, 4 construction methods completed reach the national level. The project has been awarded ＂Great Wall Cup＂ of structure and golden prize of China steel structure.
