Abstract：
Shijiazhuang international exhibition center is the world's largest cable structure exhibition hall, the main bearing structure maximum span of 105 meters, bearing structure the biggest span 108 meters, creative two-way cable structure and devoid of column design, innovative large-span cable structure is complex, difficult to install, the project uses the advanced construction technology and reasonable plan, laid a solid foundation for the project completed smoothly. Therefore, research on key construction technology of bidirectional self-anchored suspension cable structure, to provide experience and reference for other similar engineering construction.
