Large-span spatial steel structure construction is characterized by extensive spans, complex components, and highly unpredictable working conditions. Traditional construction management methods struggle to meet the demands for precision and real-time monitoring. Digital twin technology, through virtual-real integration and data-driven approaches, enables multi-dimensional mapping and dynamic simulation of construction processes, providing robust support for structural installation accuracy control, schedule optimization, and safety risk prediction. By establishing a bidirectional interaction system between physical sites and virtual models, real-time condition monitoring, dynamic process simulation, and iterative solution optimization can be achieved, thereby enhancing overall construction efficiency and reliability. This study provides technical pathways and practical references for intelligent construction and smart management in large-span spatial steel structure engineering.
