摘　　要：介绍了北京2008年奥运会三大主场馆之一的国家体育馆钢屋架的施工方案和施工技术。该屋架钢结构是国内首次应用的双张弦预应力空间结构体系,采用带索累计滑移方案高质量、顺利、安全地完成了安装,为今后同类工程的施工提供了良好的范例。It introduces construction scheme and technique for building steel roof truss of Nation Gymnasium which will be used for one main venue for Beijing 2008 Olympic Games. The steel frame of this roof truss was built by two-way stretching bowstring space stress system interiorly for the first time. It was installed successfully, securely and effectively by accumulative slippage with bowstring. This case provides a para- digm for analogous constructions in the future.
