大跨空间钢结构施工过程的数字孪生仿真

摘要

大跨空间钢结构施工具有跨度大、构件复杂和施工环境不确定性强的特点，传统施工管理方式难以满足精细化和实时化的需求。数字孪生技术通过虚实融合和数据驱动，实现施工过程的多维度映射与动态仿真，为结构安装精度控制、施工进度优化和安全风险预测提供了有力支撑。通过构建施工现场与虚拟模型的双向交互系统，可实现状态实时感知、过程动态模拟和方案优化迭代，从而提高整体施工效率与可靠性。该研究为大跨空间钢结构工程的智能建造与智慧管理提供了技术路径和实践参考。

Abstract

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.
