Abstract: The health and safety monitoring systems for large-span main carrying ropes used for wire in the National Stadium and the Daxing practice stadium were set up to Real-time Monitor the security and reliability of the large-span steel cables at Beijing Olympic Games and Paralympic Games opening and closing ceremonies. Through the comparative analysis of the real-time monitoring data and simulation value, the theoretical calculation model was verified. The result has indicated that the design of the main large-span steel cable is reasonable, its working condition and designed state is consistent, and the system is safe and reliable. It has provided a scientific decision basis for playors and props in aerial safe and wonderful performance at the Beijing Olympic games and Paralympic Games opening and closing ceremonies
