针对桥梁建设中面临的安全、技术及管理难题，本文提出一种基于数字孪生的预制桥梁吊装施工管控方法。该方法融合了“孪生预演–物联智控–数字回溯”三个核心环节，通过打通三维交互仿真平台与起重机械物联网云平台之间的数据通道，将吊装仿真预演与机械设备实时监控创新性地结合起来，并对历史数据进行系统挖掘与分析，从而实现吊装前施工方案的动态验证、吊装过程的实时监控以及核心数据的回溯闭环。工程实践表明，该方法能够有效降低复杂施工环境下多次跨高速公路吊装作业的安全风险，提升预制装配式桥梁施工的质量与效率。
To address the safety, technical, and management challenges in bridge construction, this paper proposes a prefabricated bridge hoisting construction control method based on digital twins. This approach integrates three core stages—“digital twin rehearsal, IoT intelligent control, and digital traceability.” By establishing a data connection between the 3D interactive simulation platform and the crane IoT cloud platform, it innovatively combines hoisting simulation rehearsals with real-time machinery monitoring. Additionally, it systematically mines and analyzes historical data to achieve dynamic validation of construction plans before hoisting, real-time monitoring of the hoisting process, and closed-loop traceability of key data. Engineering practice demonstrates that this method effectively reduces safety risks in complex construction environments involving multiple highway-crossing hoisting operations, while improving the quality and efficiency of prefabricated bridge construction.
